Justin Timberlake and Cameron Diaz, who announced last week that they'd split up, got into a heated argument at the Golden Globes afterparty early Tuesday morning.
They had been chatting politely during the awards ceremony and even shared laughs at InStyle's annual afterparty, it all went wrong in the small hours at a bash hosted by the singer at the Beverly Wilshire hotel.
According to witnesses, Timberlake was chatting with actress Jessica Biel when Diaz approached. Biel stepped away, and the former couple had a serious exchange.
Diaz walked away, Timberlake followed, and the two were soon spotted engaged in an intense 40-minute face-off in a side room.
Diaz reemerged looking composed, but not before Timberlake held his head in his hands and, says a witness, "slammed his fist (down) into a cabinet."
