CHRISTINA AGUILERA

Though the pop singer never officially announced her pregnancy with her first child Max Bratman (born Jan. 12), she made it proud and clear on the January 2008 cover of Marie Claire. "[People] thought I was trying to keep it this big, bad secret, and that's not the case at all," said Aguilera. "I just wasn't commenting. I'm not being like, 'Hey, everybody, I'm pregnant!' I'm not that girl."
