24. Jennifer Lopez
Jennifer Lopez shocked fans last Summer with news of her split from Marc Anthony. It didn't take long for the singer to get back into the dating pool, and she was quickly linked to dancer Casper Smart. Casper quickly grew close to her kids, Max and Emme. Jennifer and Marc seem to be on good terms, too, and have linked up to do press for their reality show, ¡Q'Viva!: The Chosen.
She dazzled audiences twice a week in primetime during her second season on American Idol. She also dabbled in film with the movie What to Expect When You're Expecting. Up next for J Lo is a role in Ice Age: Continental Drift. She's spending the Summer touring to support her album Dance Again, and has been seen as a spokesmodel for brands ranging from her own fragrance line to Harman Kardon and Fiat.
