They split-up ... But it seems they still haven't said everything the need to each other!
Justin Timberlake & Cameron Diaz met during the Golden Globes, but they chatted politely during the awards ceremony & even shared a few laughs at an after-party.
But it seems things got heated during a party held by Prince at the Beverly Wilshire hotel.
Timberlake was chatting with Jessica Biel when Cameron Diaz approached. Biel then stepped away & the former couple had a serious argument which lasted about 40 minutes!
Timberlake & Diaz then parted, going in separate ways & that was that!
I guess that must have ruined the night!
