Former best friends Drew Barrymore and Cameron Diaz cold as ice at Globes

Drew Barrymore and Cameron Diaz, who became best friends while filming Charlie’s Angels, were once each other’s sidekicks, accompanying each other out to clubs and parties all over LA.

But at Sunday night’s Golden Globes CAA after party at the Sunset Tower Hotel the former BFFs, acted more like perfect strangers.

Diaz and Barrymore both hung out at Globes bash held inside the hotel’s swanky bar/restaurant but stayed on opposite sides of the room the entire night and observers say the tension wasn’t hard to spot.

Has Cameron ditched her friends for her live in boyfriend Paul Sculfor, whom she’s rarely seen without these days?  We’re guessing there is more then that to this story but we don’t know what just yet.
