Ashton Kutcher, Mila Kunis kiss, Bobbi Kristina makes TV debut

Former co-stars Ashton Kutcher and Mila Kunis are heating things up offscreen. The pair, who used to play a couple on "That '70s Show," were spotted smooching at a wrap party for an upcoming movie in which Kutcher plays the late Apple visionary Steve Jobs.

Whitney Houston's daughter Bobbi Kristina made her onscreen debut, appearing as a sassy assistant on an episode of "For Better or Worse" on TBS. The budding actress later thanked her fans on Twitter for their "support and love."

Also new to TV is Mariah Carey, who has been officially announced as a judge on "American Idol." The pop phenomenon, who boasts more No. 1 singles than another solo artist ever, will critique hopefuls when the show returns in January. In the meantime, let us know whether you think Carey will make a good "Idol" judge.
