Britney Spears has teamed up ya'll with Will.i.am for the infectious new single "Scream & Shout" ... and the new music video is hot!

The mama of two is workin' a sexy black mini and showing off her fab legs. Will.i.am had the right idea when it came to choosing a partner for a duet.

The single is off Will's upcoming album Willpower. Loves it!

Halle Berry is unloading her West Hollywood estate for $15 million following the fight between fiance Olivier Martinez and ex Gabriel Aubry.

The brutal brawl took place on Thanksgiving day in the driveway of the 5,900 square-foot property.

The 46-year-old Oscar-winning actress' pad boasts 5 bedrooms, a pool, a spa and a 1,400 square-foot guest house.

Halle bought the house from actor Frankie Muniz back in 2005 for $6 million.

Berry also owns an $8.5 million beachside home in Malibu.

I think we can all agree we would much rather see this Brazilian beauty in that get-up!

Alessandra Ambrosio made an appearance Wednesday on Chelsea Lately, and the model was welcomed by the talk show host's sidekick Chuy Bravo, who spoofed the catwalker's runway look in a diamond bra and angel wings. Yikes!

The 31-year-old knows a thing or two about lingerie covered in precious stones! She was bestowed the honor of wearing the Victoria's Secret Fantasy Bra for the runway show last month, which was covered in 5,200 precious stones and valued at $2.5 million.

Miss Ambrosio stayed much more covered up for the sit down, donning a white minidress and red Louboutin heels that showcased her mile long legs.

Leave it up to Chelsea to turn anything into a joke!

Just a few days ago, Britney Spears introduced the world to her new puppy Hannah. Seems like this little doggy is now glued to Brit's hip!

The X Factor judge took her new pet to work ... with the little pooch nestled underneath her arm. We also love seeing that engagement ring bling, Brit! Fiance Jason Trawick followed behind with Hannah's animal print doggie bed.

Jason even joked around by wearing the fluffy bed as a hat. Lucky dog. Yes, Hannah, too!

Congrats to the happy parents!

Guy Ritchie and his fiancee Jacqui Ainsley welcomed a baby girl at a private London hospital, their rep confirmed to Daily Mail.

"We can confirm that Guy and Jacqui are the proud parents of a new baby girl. Mother and baby are doing well," the rep said in a statement.

This is the second child for the couple, who welcomed son Rafael in September of last year. Ritchie and Ainsley have been dating since spring 2010, and became engaged last month.

This new addition makes the British director a father-of-four! He also has son Rocco, 12, and adopted son David, 7, from his first marriage to Madonna.

The infant's name has yet to be released.

What a fantastic early Christmas present!

Talk about taking it off!

Wendy Williams became the latest celebrity to strip to support PETA for their no fur campaign as she unveiled her billboard in Times Square on Wednesday.

The 48-year-old TV personality voiced her disinterest for fur but had another risque reason to help their campaign. "As a talk show host, where everything has got to be so covered up during my show, I welcome the reasoning to go naked," Williams said. Someone's certainly not shy at all!

On Wednesday, Kim Kardashian's divorce lawyer revealed that her client is unable to move on from estranged husband Kris Humphries but is still his legal wife due to the delay of their trial.

"Ms. Kardashian is now handcuffed to Kris Humphries," Laura Wasser told L.A. Superior Court judge Stephen Moloney on Wednesday. "These delays are forcing her to be married. She wants to dissolve her marriage so she can move on with her life. I don't think [Kris] has a case, it's a fishing expedition."

One of the reasons for the delay is due to Humphries' lawyers asking for more time to seek an annulment based on fraud. Humphries has claimed Kardashian "had no intent of being married" and that it was all "for the benefit of her TV show."

Moloney has told their respective attorneys to return to court in mid-February to set a trial date to either dissolve or annul the couple's 72-day marriage. Although no deadline has been set, he indicated that a trial could start early next year if everything's ready by Feb. 15.

Liam Hemsworth was looking pretty casual as he braved a rainy Los Angeles afternoon to hit the studio on Wednesday.

The 22-year-old actor was probably tying up some loose ends since he'll soon be heading to Atlanta to begin shooting The Hunger Games: Catching Fire. We're sure he and fiance Miley Cyrus will get in some alone time before he goes!
