JT & Cammie's afterparty spat

Cameron Diaz and Justin Timberlake reportedly had a heated run-in at a Golden Globes afterparty on Monday night. Diaz is said to have flown into a jealous rage when she spotted Timberlake chatting with Jessica Biel. The Illusionist actress stepped away while Diaz and Timerlake had a forty minute argument, after which Timberlake "slammed his fist into a cabinet," according to a witness. "If that's how she wants to get him back, it won't work," said an insider. "She's desperate." Meanwhile, the SexyBack singer is allegedly seeing Scarlett Johansson after Timberlake hand-picked the Scoop actress to star in his What Goes Around video. "They're just having fun," says a friend of the potential couple.
