Fergie, who has stood by her actor spouse despite allegations he slept with a stripper, a story he has denied, openly admits to being bisexual and says she had to learn she couldn't have extra-marital affairs with either men or women,

Contactmusic reported.

"I've been very honest with him from the get-go. 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. But just because I enjoy women doesn't mean I'm allowed to have affairs in my relationship," Fergie said.

"I learned through talking with my therapist that it is still cheating even if it's with girls, so there is a rule there," she added.

The couple's marriage was recently rocked by allegations the Duhamel had cheated on his wife with a stripper.
