Are Cameron Diaz and Drew Barrymore BFFs No More?

Once upon a time, Cameron Diaz and Drew Barrymore were inseparable lifemates who strolled down the streets of Los Angeles with their arms linked, a sign of their girlish allegiance. These days? Not so much!

Anyone watching the Golden Globes on Sunday could see that Drew has found herself a new hip-attachment (Jessica Lange, her new co-star in the upcoming movie, Grey Gardens), but now we're hearing that she and Cameron were even more distant behind the scenes. OK! says the two stars "ignored each other all night long" at a CAA-hosted Globes afterparty at the Sunset Tower Hotel, and a partygoer confirms that they didn't even exchange words:

"Both Cameron and Drew were at the party but neither one spoke to each other!" a fellow party goer tells OK!. "They were on opposite sides of the room the entire night."

The reason for Cameron and Drew's beef with one another is unclear, but the gossip mag is happy to speculate that Cam's new live-in boyfriend, Paul Sculfor, could be a factor: "Has Cameron ditched her friends for her man?" it asks. "Now that Cameron has been seriously dating model Paul Sculfor, she's rarely seen without him."

Never mind that Cameron walked the red carpet solo on Sunday night! Or, that there were no sightings of Paul at the Golden Globes fête. Whatever the reason, we hope these two gals make up soon, because Cameron makes a much hotter sidekick than Jessica Lange.
