Are Cameron Diaz and Drew Barrymore girlfriends or girlfriends? The actresses bonded after co-starring in 2000's Charlie's Angels, and though Barrymore is married to art consultant Will Kopleman, gossipers have speculated for years that they're more than just friends.

Earlier this year, Diaz told Glamour U.K. that she believes "all women have been sexually attracted to another woman" and revealed on Bravo's Watch What Happens Live that she has "been with a lady." Diaz's revelations reignited rumors that she'd hooked up with her BFF in the past. Cameron says, "Some media outlet called for a comment and they wanted to know whether I was with Drew. Literally, I said, 'That makes me want to vomit in my mouth.' That's like saying I'm having sex with my sister."
