Actor Nick Stahl, who played John Connor in "Terminator 3: Rise of the Machines" and was reported missing by his wife last week, has told friends he is entering a rehab facility, his wife tells PEOPLE.com.

Rose Stahl said she was "relieved" but also "skeptical" that the actor was actually entering rehab, according to the PEOPLE report.

Stahl's wife had reported him missing last Monday.

Police said Stahl had been frequenting Los Angeles' skid row and officers on that beat had been told to be on the alert for him, according to a Los Angeles Times report.

Jenna Talackova, the 23-year-old woman who forced Donald Trump and his Miss Universe Canada pageant to end its ban on transgender contestants, fell short of the national title Saturday night at the pageant in Toronto.

The crown went to Sahar Biniaz, an Indian-born, Iranian-raised actress from Vancouver. Biniaz, 26, will represent Canada at the Miss Universe pageant in December, according to the Miss Universe Canada website.

Talackova didn't walk away from the pageant empty-handed. In addition to finishing among the top 12 semi-finalists, Talackova tied with three other contestants for the title of Miss Congeniality.

The road map out of the war in Afghanistan is expected to be drawn up by U.S. President Barack Obama and other world leaders when they gather Sunday at the NATO summit in Chicago.

Against a backdrop of massive protests - and a foiled, homegrown terror plot that targeted Obama and others - the summit will open with NATO countries trying to figure out how to meet a 2014 withdrawal from an unpopular war while shoring up Afghanistan's security forces.

Security is expected to be tight at the summit following the arrest of three men, described by authorities as anarchists who plotted to attack Obama's Chicago campaign headquarters and lob Molotov cocktails at police during the summit.

Police insist there are no imminent threats to the leaders of more than 50 nations gathering at the summit.

Iran's finance minister believes oil prices could rise as high as $160 a barrel thanks to sanctions over its nuclear program, a prediction that comes just as the chief of the United Nations nuclear watchdog agency headed to Tehran on Sunday for high-level talks.

"We must pay close attention when we speak of oil revenues and sanctions against oil sales, who are the winners and the losers of such sanctions?" Shamseddin Hosseini told CNN's "Fareed Zakaria GPS" in an interview that airs Sunday.

"Indeed, it is difficult. But not just for Iran. And we can all rest assured that there will be a considerable increase in international oil market prices. Now, is this the best approach?"

The comments came as the International Atomic Energy Agency said in a carefully worded statement that its director-general, Yukiya Amano, was headed to Iran for talks on what it described only as "issues of mutual interest with high Iranian officials."

A strong earthquake struck early Sunday in northern Italy, killing at least three people and knocking down a church bell in the region, authorities said.

Two people were killed in a ceramic factory in Sant'Agostino di Ferrara, and one person died when a workshed collapsed in Ponte Rodoni di Bondeno, according to Elisabetta Maffani, spokeswoman for Italy's civil protection agency.

The 6.0-magnitude quake occurred just after 4 a.m. (10 p.m. ET Saturday), 4 kilometers (2.4 miles) outside Camposanto, northwest of Bologna, the U.S. Geological Survey said.

The Italian civil protection agency said it anticipates more injuries as rescue workers make their way to remote villages in the mountainous area.

Tropical Storm Alberto, the first named storm of the 2012 Atlantic hurricane season, formed Saturday off the coast of South Carolina.

As of 5 p.m., the storm was located about 140 miles east-southeast of Charleston, South Carolina, with maximum sustained winds of 45 miles per hour, the Miami-based National Hurricane Center said.

It was churning southwest at 3 mph.

No coastal watches or warning were in effect, though a tropical storm watch could be issued for parts of the coast later Saturday, the Hurricane Center said.

The rocket engines of SpaceX's Dragon spacecraft fired, and then abruptly stopped as the countdown to launch reached zero on Saturday. The shutdown caused SpaceX to abort launching the private unmanned spacecraft to the International Space Station.

Both NASA and SpaceX want Dragon to be able to deliver cargo to the station, bringing food, water and other provisions to the station's crew. The possibility of this launch was regarded as historic for sending private spacecraft into orbit.

Editor's note: This post is part of the Overheard on CNN.com series, a regular feature that examines interesting comments and thought-provoking conversations posted by the community.

It's Friday. Let's end the week by taking a look at some funny comments about stories in the news. First, we venture backwards in time to your teenage years.

New French PM's name causes Arab giggles

Prime Minister Jean-Marc Ayrault's name sounds like Arabic slang for male genitalia. Some thought this story might inspire kids to learn foreign languages.

Uncle_Dutch: "Some people never get out of junior high. On a positive note, it might be just the spark to get the Beavis & Butthead types of this country to finally learn a foreign language."

readerz: "Vastly educational. We just learned two new words in Arabic, in the long-standing tradition of every foreign-language student who looks up all of 'those' words first. I hope that Mr. Ayrault and (Pakistani diplomat Akbar Zeb) continue to educate. At least the article did not use Victorian English, where there is another word used in place of the word 'said.' Reminds me of something produced by Congress, but maybe the language would need to be aborted."

Politicians with dirty-sounding names are nothing new, readers say.

Niki Bush: "If we can get over the fact that two of our presidents were Bush, then we can get over the fact that the French (prime minister) president's name means penis in the Arabic world. I had an uncle named Richard Head, and when you go through your entire life with the last name that is an euphemism for the downtown area, every other wacky name just isn't really all that funny."

Some people are all too familiar with this issue.

JanetMermaid: "Seriously? I used to work with a Harry Biggrigg and a Harry Biggerstaff - both at the same company. And I went to school with a Dick Holder. Sounds like a few folks need to grow up."

GDINY2: "Just as in my company, everyone is a Richard Head."

Kris Jackson: "Hey, ask John Boehner his opinion. Or Dick Armey. Kinda makes me wish Anthony Wiener was still around."

Some had a little fun with the Farsi word "kir."

CyrusIII: "Hahah ... The President of South Sudan's name (Salva Kiir) also means penis in all the Iranian languages ..."

EVinSB: "The Indians have this dessert called Kheer which is pronounced the same way (Kiir). Whenever I order it I have to do a double take and make sure I'm not ordering penis."

When in Ireland ...

Chimbok: "'Bod' is the name in Irish for the word in the subject matter. So, when you see a nice woman, and tell the person near you, 'Man she has a nice bod,' then what the heck are you saying?"

Females are not exempt from such terms, as written by one user.

"Maybe some brilliant CNN reporter should tell us how the Arabs react to eating a dish called 'cous cous.' "

Don't forget about the planets.

pmalte: "I read that the name of the planet Uranus ... has actually had an impact on the number of people who decide to study the place, reducing the number of scientists who don't want to their life's field of study being giggle-inducing. TV shows that try to play it coy by pronouncing it 'urine-us' only make it funnier. It always triggers a whole spate of jokes in my family, who love watching shows on astronomy: 'Did you know the temperature on Uranus is near absolute zero?' or 'The surface of Uranus is full of cracks and fissures.' And don't forget, 'There are no signs of life on Uranus.' "

Now, we look at the social behemoth known as Facebook, used by nearly one in seven people on earth and now being publicly traded on the stock market as "FB."

Why I won't be quitting Facebook

Readers expressed cynicism. In fact, many said they don't use Facebook. But some do. Does it resemble coastal New Jersey?

malibu66: "Something just occurred to me. This is the new reality TV. Except you get to have a few people you know personally in the show. It's like Jersey Shore with people in your life. Not my thing, but it is now how I see it."

This reader has a new term for Facebook.

Gumpy52: "A year ago I told the 16 people working for me in my office that I did not want them on Facebook during business hours. or shopping on eBay. Three of them must have thought I was joking. They're now unemployed. Now, they can spend all day on Facebook. That's why it's called 'Social Not-Working.' "

One could assume this person is a fan of some other company.

Rumpel Stiltskin: "When Facebook makes a car that can drive itself and gets it registered in Nevada then I will like them too."

But do think about your online privacy, even on Google.

Rumpel Stiltskin: "I mean when you're signed into Google and you do an image search for grannies with hot fannies how can you not be embarrassed knowing they have that on file."

hollowkiller: "If you don't want to see that, just turn on the safe search so you won't have to gouge out your virgin eyes. Works for me."

Guest: "I'm hoping they'll somehow let grannies with hot fannies know I'm on the hunt for them."

copanut: "Easy. Don't sign in."

Hold on to those grains of salt, folks.

jdr24: "My girlfriend posted a picture of me in front of my birthday cake last night. I have no life, my girlfriend has no life and all of my friends that see it have no lives. She should've spent 15 productive minutes composing an email to send it to all of them instead, but alas she failed and devastated us all in those 5 horrifying seconds. On top of that, the government, employers, hackers and ad companies are hard at work milking all possible information they can from that picture so that they can further devastate my already lacking life. Indeed, anyone who uses FB is surely damned."

If you are planning on heading out to the movies this weekend, the new film "Battleship" will be one of your options.

Review: The captains of 'Battleship' deserve a medal

The classic board game inspired a few readers' creativity.

zrxgrim: "I can't wait for Michael Bey's 'Hungry Hungry Hippos' in 2014!"

plank: "Look at Robot Chicken - they already noted this along with Chutes and Ladders ..."

BjammindD: "I admit, I laughed. Cue the Michael Bay-style over-dramatized voice-over: 'GOBBLE THEM ALL UP!' *explosion*"

NyuBomber: "Quentin Tarantino presents ... Candy Land."

Look like fun to you?

Buddy9876: "Blam! Kapow! Sploosh! Whoosh! CGI flames and explosions! Count me in! (Seriously - no sarcasm here. I'm totally into that kind of thing.)"

waltonsimons: "Out of curiosity, who was asking for a 'Battleship' movie to be made? Were there really
'Battleship' players out there who, after a few well-fought rounds, stopped and said to themselves, 'You know what would be awesome? If this game was a movie!' ?' "

vulpes08003: "I did."

In other popular culture news, some fans of Van Halen could be a little disappointed to hear that the band has canceled 30 stops on its current tour. They still plan to play through 13 shows, however.

Van Halen postpones 31 concert dates

Here's one theory from one reader apparently familiar with the band.

SnackMonster: "It was postponed because the high 'E' string on (Eddit Van Halen)'s guitar is crafted from the ground up dust of baby unicorn horns, and there was an unexpected shortage in the supply chain recently. They tried the substitute string made out of leprechaun tendons but Eddie threw a fit and claimed that the 16th harmonic faded out 20 nanoseconds too soon. Totally unacceptable to his ear. If you know or have ever worked with EVH you will know exactly what I am saying "

PVS1: "Give the guy a break, man. He actually got rid of the guitar chord he was tripping over all last tour and went wireless, which (as you well know, im sure) must have required a pure leap of faith on his part."

SnackMonster: "I know ... and the only way he agreed to that was because we convinced him that it was an invisible cord made out of fibers from the corneas of seahorses."

Harry Stone was on one of his usual jogs in a Kansas City suburb shortly before 7:30 a.m. Sunday when an approaching car slowed down and a passenger shot him.

The vehicle kept going without stopping, and Stone, 60, later died at a hospital.

Nearly a week later, police in Raytown, Missouri, say they have no suspects, and no one has any idea why he was targeted.

He wasn’t robbed. He didn’t have any known enemies. And a gang-initiation hit appears implausible, Raytown police Capt. Ted Bowman said.

“Even grasping at straws and imagining motives, we have been able to find nothing in the man’s background or time or place or associations or his relationships or his history,” Bowman said Thursday.

“Literally, we can find no motive,” he said.

Stone was a homeowners’ association leader and the husband of a pastoral assistant – she was supposed to preach Sunday morning at Raytown’s St. Luke United Methodist Church, CNN affiliate WDAF reported.

He was shot near an intersection by a gas station. Surveillance video from the station shows the shooting, though police have released only footage of a few seconds before the shot, Bowman said.

The video shows a dark-color, four-door car. Police say they don’t know the model or the license plate number. Bowman said a witness was able to describe only the passenger, and the description was light on details: a young African American male with a short Afro-type hairstyle.

A Kansas City police spokesman, representing a multiagency detective squad that looked into the shooting, initially told local media that the killing could have been part of a gang initiation, as CNN affiliate KCTV reported.

But Bowman said Thursday that detectives have determined this probably wasn’t the case.

“We have not found any of the street gangs, that we’re aware of, to make that an open part of the initiation process,” he said.

People who knew Stone told KCTV that he enjoyed serving others, doing things such as helping to build a park next to his church. His daughter, Susan Li, told reporters Monday that he prided himself in keeping physically fit and hoped to get back into running marathons.

Li asked for people with information about the shooting to come forward.

“He was in constant service … to the community, and the community now has the opportunity to be in the service of justice,” she said.

In a move to make sure Afghan women’s issues are not forgotten during the upcoming NATO Summit in Chicago, Amnesty International USA is hosting on Sunday a Shadow Summit to focus exclusively on the rights of Afghan women and girls.

The summit will culminate with attendees gathering at Chicago’s Navy Pier to fly kites in support of Afghan women’s rights.

The concern of those who will attend the summit is this: What happens to Afghan women and girls after the United States and allied forces move to withdraw in 2014?

The question about what the troop withdrawal will mean for women and girls in war-torn Afghanistan is not new. It was the question posed on the cover of Time magazine in August 2010, next to the photograph of a young woman who became the symbol of the oppression of Afghan women.

The award-winning image was that of Aesha Mohammadzai, then known as Bibi Aisha. Forced into marriage at a young age, her Taliban husband and in-laws punished her for running away by hacking off her nose and ears and leaving her for dead.

She was brought to America for reconstructive surgery in August 2010. But what has happened to Aesha since she arrived nearly two years ago?

Coming Sunday, CNN’s Jessica Ravitz will answer this question in an exclusive story that traces Aesha’s complicated journey.
