Star Tracker: Jennifer Lopez, Marc Anthony and Christina Aguilera

Christina Aguilera is defending herself against critics who called her recent performance on the British TV show, X Factor, too provocative. "I don't think there is such a thing as too raunchy when it comes to the art form of burlesque," said the singer.

The CW's new hit show, Hellcats, which stars Costa Rican actress Heather Hemmens, will move from Mondays to Tuesdays at 9/8c when the show returns for its back nine episodes on January 25, 2011.  

J. Lo's bitter first hubby, Ojani Noa must (finally) be tired of suing Jennifer Lopez, so now his ex-girlfriend Claudia Vazquez is having a go at it! In a $10 million lawsuit filed in Los Angeles today, Vazquez charges that J.Lo interfered with a motion picture contract between her and Ed Meyer.

And speaking of J-Lo, she and her hubby Marc Anthony made a surprise appearance at the birthday party of Marcelo Claure, the founder and CEO of the Miami based Brightstar Corp.  Marc performed for an hour and half in honor of Claure and surprised the audience of about 750 guests by inviting his wife up to perform their duet, No Me Ames.
