Selma Blair held on tight to her adorable baby boy Arthur while braving the New York chill. The little cutie, wearing a beenie and oh-so-stylish booties, has the most gorgeous blue eyes!

Although daddy Jason Bleick was nowhere in sight, looks like Selma is doing just fine on her own.

Mary-Kate and Ashley Olsen cover Vogue magazine's Best Dressed Special Edition, and the twins were voted the most stylish sisters of the year.

Vogue also included Kate and Pippa Middleton, Beyonce and Solange Knowles and the Fanning sisters in this issue, so not only is there plenty of couture to feast your eyes on, but there's also a splash of sibling rivalry!

Editor Mark Holgate told Reuters, “They get it right a lot of the time and then sometimes they don't get it right. That's actually great ... They don't have someone telling them, 'This is cool, this is hot, this is what you should be wearing.' It comes from within them. It's instinctual.” It certainly is!

Oooh this looks GOOD!

We got our first peek at Snow White and the Huntsman at Comic-Con this past summer, but here's an extended trailer for the film, and not only does Charlize Theron totally embrace the role of the Evil Queen, but the visuals look spectacular! Of course, we can't get enough of her co-stars Chris Hemsworth and Kristen Stewart -- the only bummer is that we have to wait another eight months to see this on the big screen!

Ashton Kutcher was once a pioneer of Twitter. In 2009 he challenged CNN to see who could reach 1 million followers first, and won.

Two short years later, he has more than 8 million followers and, especially with recent months of heated news over his alleged cheating on wife Demi Moore, his Twitter account is monitored constantly by the media and fans.

On Wednesday, the actor got major heat for Tweeting that Penn State University coach Joe Paterno's firing was unfair. Kutcher, an advocate in the fight against child sex abuse, quickly apologized (also via Twitter.) He said he did not know the full story -- that Paterno allegedly ignored that one of his assistant coaches had sexually abused young boys.

On Thursday, Kutcher Tweeted a blog post in which he says that Twitter has become too much for him, and he will handle the management feed over to his production company team, Katalyst Media.

"As of immediately I will stop tweeting until I find a way to properly manage this feed. I feel awful about this error. ... twitter has grown into a mass publishing platform, where ones tweets quickly become news that is broadcasted around the world ... I feel responsible for delivering an informed opinion and not spreading gossip or rumors through my twitter feed."

Kutcher said he instantly received, "... a hailstorm of responses calling me an 'idiot' and several other expletives that I've become accustom to hearing for almost anything I post" after the Paterno Tweet.

Mariah Yeater, 20, is demanding that pop star Justin Beiber, 17, take a paternity test to determine that he is the father of her 4-month-old son after a tryst last year.

Bieber's camp says he has scheduled a paternity test for two weeks from now, when he returns from Europe, where he has been performing and spending time with girlfriend Selena Gomez (see photos of the two in Paris below!)

On Wednesday, Yeater's lawyers said they had first tried to settle with the pop star out of court. Chicago lawyer Jeffrey Leving said he sent e-mails to Bieber's camp in September and October asking for a private paternity test and negotiations for child support; he said that, at the time, he and Yeater saw no need for a public court filing.

“It could have been done painlessly, with the media never knowing about it,” he said.

Leving says he trusts Yeater's story, and wants to make sure that Bieber's DNA test is done properly. “People are so enamored with Justin Bieber, you could have someone change samples in a lab because of love for this guy," he said.

A court hearing is scheduled for Dec. 15. Read about Yeater's criminal past after the jump.

Blake Lively and Ryan Reynolds co-starred in The Green Lantern, and now they're reportedly looking to cohabitate.

The two have only been seeing each other romantically for about a month; Lively began dating Reynolds quickly after splitting from summer fling Leonardo DiCaprio.

But The New York Post says the actress, 24, and actor, 35, were spotted looking at NYC apartments together, including a three-bedroom, $4.35 million penthouse on famous Fifth Avenue in Madison Square Park.

"When they were done, she left the building first, wearing tall boots, jeans, coat and fedora, and got straight into a Town Car, and then Ryan exited into the same car," the Post's source said. "Her little dog was waiting with the driver in the front seat."

Lively lives in Chelsea -- she's in NYC most of the time to shoot Gossip Girl.

Perhaps she even had a few spirits last night?

Chelsea Handler was snapped leaving Tavern in Brentwood on Wednesday evening, and the comedienne appears to be handling her split from hotelier boyfriend Andre Balazs quite well.

"She's fine," a source recently told Page Six. "If she's feeling down, she's certainly not showing it." Handler and Balazs dated for seven months, and she previously dated rapper 50 Cent, Animal Planet host/hottie Dave Salmoni and NBC executive Ted Harbert. Hmm, wonder who she'll date next?

After five years on America's Got Talent, Piers Morgan is leaving his spot at the judging table. Morgan made the announcement on Wednesday night's episode of Piers Morgan Tonight, explaining that he needs to focus his efforts on his evening talk show.

"I've loved every single second, but discovered that juggling, to my surprise really is a bit more difficult than I thought," Morgan added. Morgan thanked America's Got Talent creator Simon Cowell for the opportunity to work on the show, and he even joked to the Motion Picture Academy that he is now available to host the Oscars.

Do you think Piers would be a good replacement for Eddie Murphy?
