IT MAKES SENSE NOW! FERGIE ADMITS TO BEING BISEXUAL! THAT'S WHY SHE'S NOT MAD @ HER HUSBAND FOR SLEEPING WITH THE STRIPPER!

As rumors fly that Fergie's husband cheated on her, she unleashes juicy stuff about her own sex life.
The singer, 34, tells the Advocate that her hubby, Josh Duhamel, is "well-endowed" and confirms that she's bisexual.

In the interview, which was conducted before the recent rumors that Duhamel had sex with a stripper, Fergie says she's been honest with her famous husband about her bisexuality from the beginning.

"I think women are beautiful," she says. "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 adds. "I learned through talking with my therapist that it is still cheating even if it's with girls, so there is a rule there."

The same rules don't seem to apply for Duhamel though.

The "Transformers" star allegedly cheated with a blonde stripper on Oct. 9, just nine months after he married the singer, according to The National Enquirer.

The stripper, Nicole Forrester, told the Enquirer that she met Duhamel in an all-nude club in Atlanta, where he was in Georgia filming "Life As We Know It."

Forrester claims they exchanged phone numbers, and he later invited her to his hotel room where they had sex. Fergie is standing by Duhamel, who vehemently denies the report.
