According to People magazine, Diaz and Timberlake got into an arugment at an after party following the Golden Globe Awards.
Last week, the two stars announced their split. During the Golden Globes, they exchanged niceties, but they were much less amicable during a party at the Beverly Wilshire Hotel.
The singer was talking to actress Jessica Biel when the Charlie’s Angels star approached. Biel excused herself, and Diaz, 34, and Timberlake, 25, argued for nearly 40 minutes.
