Pop star Fergie talks about what she considers cheating.

Prior to reports that her husband Josh Duhamel had an affair with an Atlanta stripper, the singer opened up to The Advocate about her bisexuality and what that meant for her marriage. "I think women are beautiful, I've had a lot of fun with women, and I'm not ashamed of it. The problem is that I also love a well-endowed man," she told the publication. "But just because I enjoy women doesn't mean I'm allowed to have affairs in my relationship. I learned through talking with my therapist that it is still cheating even if it's with girls, so there is a rule there."

When asked if Fergie and Josh have ever made a sex tape, the singer responded, "No, that's not happening. We're too smart for that. We've done some filming but with no tape in the camera."

The sexy superstar shows off her musical abilities and acting chops in the film 'Nine,' hitting theaters Christmas day. Fergie's interview in The Advocate will be on newsstands Nov. 24.
