Cameron Diaz Says the Idea of Having Sex With "Sister" Drew Barrymore Makes Her "Want to Vomit"

"I wouldn't even ménage with her!" the actress tells Harper Bazaar of having a threesome with her BFF

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. But because they've never even fooled around, Diaz tells Harper's Bazaar she doesn't "pay attention" to nonsensical gossip.

"People will always speculate. People like scandal. They like to put a label on something that they don't understand," explains the Sex Tape star, who is dating Benji Madden. "It makes them feel comfortable."

At times, the speculation gets out of hand. "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," she says. "Are you crazy? I wouldn't even ménage with her!"

As far as sexual exploration goes, Diaz believes it's important to keep an open mind. "Everybody tries things and sees things and checks them out, and either walks away or walks further in," she reasons.

Experimentation is normal, she adds. "It's life—it's what people do. I'm not going to tell people what I've done, but I'm also not going to say, 'No! I would never!' If I said that, I'd be shaming myself and shaming other people's choices," she tells the magazine. "I don't want to add any stigma to someone's choice."

Diaz also opens up about getting older and attracting attention for being childless and unmarried in her forties. "What I said, always, and how I still feel, is that if I wanted to have a child in my life, I would have a child in my life," she explains. "I don't know what life has ahead of me. I'm open. Anything is possible."

Aging scares some people, but it invigorates Diaz. "I know there are a lot of things you lose when you get older but there's so much you gain. Why would I want to stay 22 when I can be 62?" she wonders. "I think 62 is going to be a lot better than 22. I don't want any of it back. I just want to move forward."

Diaz's feature appears in Harper's Bazaar's August 2014 issue, on newsstands July 22.
