Some rumors were flying around for awhile when Cameron Diaz admitted on "What What Happens Live" in April that she once experimented relations with the opposite sex. Then everyone suddenly thought of Drew Barrymore. Cameron has told Harper's Bazaar that Drew isn't the one.

Because Drew is like a sister:

“People will always speculate. People like scandal. They like to put a label on something that they don’t understand. It makes them feel comfortable. Mostly they like to guess who it could be. 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. Are you crazy? I wouldn’t even ménage with her!”
