Check out the VIDEO of Cameron Diaz leaving Los Angeles amid reports that her and ex-boyfriend Justin Timberlake were spotted having a heated argument during Monday nights In Style Golden Globes after party. Page Six reports:

CAMERON Diaz is not over Justin Timberlake just yet, and things got heated when she saw her ex chatting up Jessica Biel in L.A. after the Golden Globes. Sources say the temperamental star "blew up" at Biel after she saw Timberlake flirting with her. Diaz followed Timberlake to the In Style party at the Hilton Oasis, where "they had an awkward conversation." The "Charlie's Angels" star then trailed Timberlake to the Beverly Hilton rooftop for the Universal party, where she found him chatting up Biel - and screamed at the "Illusionist" star. "If that's how she wants to get him back, it won't work," said our insider. "She's desperate." Reps for Diaz did not return our call.

See celebrities are just like you and me! When people like you or I get dumped we sit in the parking lot of the Taco Bell (Church's Chicken if you live in Louisiana) that our ex works at stuffing our faces with Gorditas with hopes of creating a scene at the Drive-Thru while Cameron Diaz does it at a Golden Globes party stuffing her face with caviar and champagne.
