Fergie knows the rules, even if her husband, Josh Duhamel,doesn’t. Stripper Nicole Forrester recently claimed she had sex with Duhamel, but the “Las Vegas” star called the story “absolutely ridiculous.” Fergie (pictured) might not believe him, but she believes in monogamy. She told The Advocate: “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. I learned through talking with my therapist that it is still cheating even if it’s with girls, so there is a rule there.”
