Jennifer Lawrence and her Hunger Games co-star Josh Hutcherson attended a special signing event at Barnes & Noble in New York City last night, and hundreds of fans lined up for their chance to meet the stars. The movie hits theaters on Friday, but we have a feeling the craziness will only continue to grow once we get our first peek at Katniss, Gale and Peeta on the big screen!

Jennifer posed for a few shots with Josh, and no offense to Vanessa Hudgens' former flame, but Jen absolutely stole the show in this low-cut green Calvin Klein Collection frock:

Madonna has released the music video for "Girl Gone Wild" and the 53-year-old singer still has all the moves -- and plenty of ways to get critics talking!

Fashion photographers Mert Alas and Marcus Piggott directed the sexy black and white vid, and this is the Material Girl's second single from her upcoming 12th studio album, MDNA, out March 26. Check it out!

When you're as famous and sexy as Rob Pattinson, you can dress down for a business meeting in Beverly Hills.

The Twilight hottie, wearing dark jeans and a plaid shirt, showed off his edgy buzzed 'do and bushy beard. We have to admit, this grungy look suits RPatz just fine!

It's no secret that the 25-year-old actor is a fan of multiplayer online role-playing games. Check out his shirt! Shadow Dragon is one of the hottest games around.

Perhaps we'll see RPatz fighting dragons on the big screen in the near future. No doubt, girlfriend and Snow White and the Huntsman star Kirsten Stewart can give him lessons on how to swing a sword!

Oscar-winning actress Reese Witherspoon is going to be a mama for the third time! The blonde beauty is already sporting a tiny baby bump.

The This Means War star, who turns 36 this week, is now twelve weeks along.

A source tells Us Weekly:

"Reese and Jim have been trying to get pregnant. The timing is right. She's so happy!"

This will be her third baby and the first for husband Jim Toth. Reese and ex husband Ryan Phillippe are the parents to Ava, 12, and Deacon, 8.

When Suri Cruise says she's wearing pajamas to dinner, you don't argue!

Making her way to trendy eatery ABC Kitchen in NYC on Tuesday evening, the stylish 5-year-old looked comfy in her matching jammies paired with a purple suede coat and silver ballet flats, while mom Katie Holmes kept it casual in a white angora sweater and jeans.

But little Miss Cruise seemed to be on the verge of a temper tantrum as they hurried to meet Grandma Holmes for dinner, until Holmes finally agreed to pick her daughter up and carry her the rest of the way!

The girls are gearing up to send some quality time in the Deep South next month, where Tom Cruise will be work on his latest film; an untitled sci-fi action thriller will film in Baton Rouge and New Orleans. Don't forget to pack the bug spray, Kate!

After solidifying her newly single status by stepping out sans wedding ring this week, Jennie Garth is finally speaking out about her split from Peter Facinelli, and how their three daughters are coping.

"My life is a little hectic right now and my personal life is kind of crazy," the Beverly Hills 90210 star confessed to Access Hollywood Live, adding that her upcoming reality show, CMT's Jennie Garth: Little Bit Country, is "what I need and what the girls need right now."

The show will feature Garth and her daughters Luca, 14, Lola, 9, and Fiona, 5, as they try out life on a farm outside of LA city life, but the actress insists she had "had no idea" that a split with the Twilight star was in her future when she signed on for the series.

Jennie also added that her girls have been "doing great" since the split.

Busy celeb Jessica Alba never forgets she's a mother first, which is why she was seen carrying a huge family portrait into her Honest Company offices in Santa Monica, on Tuesday afternoon.

The professional pic is definitely magazine-worthy, and features Alba in a rocking chair holding baby Haven, while her 3-year-old daughter Honor plays on the floor with hubby, Cash Warren.

Aside being an actress/mother/wife/CEO, the Fantastic Four star is about to add "author" to her growing list of achievements!

Alba has just announced that she plans to release her first book, "The Honest Life," in 2013, which will give recipes and advice on how to live a healthy and non-toxic life. We're just looking forward to making Honor's favorite meatball recipe!

All of that hard partying down at the Shore has finally taken its toll on Mike "The Situation" Sorrentino!

It was reported this week that the Jersey Shore reality star has checked himself into an undisclosed treatment program, but denies that its for the treatment of substance abuse.

Sorrentino's rep revealed in a statement on Tuesday:

"He has spent the past several weeks at an undisclosed location for much needed rest and recuperation after his extensive production and appearance schedule."

While it is still unclear if Sorrentino will officially rejoin the cast when MTV begins filming its sixth season, he recently Tweeted, "Getting in amazing shape for season 6."

Get well soon, Mike!
