Fergie “loves a well-endowed man” which may go some way to explaining why she's stuck by husband Josh Duhamel amid rumours of his alleged infidelity.

The Black Eyed Peas star chats about her sexcapades - and the subject of cheating - with both men and women in a very frank new interview.

"The funny thing is that I was very open and honest about that from the very beginning, and everyone was acting like it was some new trend," she tells the Advocate.

"Go back four or five years, people, and you'll see the same answer."

Josh, perhaps unsurprisingly, is cool with her bisexual past.

"I've been very honest with him from the get-go," she says. "I think women are beautiful. I've had a lot of fun with women, and I'm not ashamed of it.

But, she adds: "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."

Despite being open about experimenting in the bedroom, don't hold your breath for a Fergie sex tape.

She reveals: "We've done some filming but with no tape in the camera."

Josh denies tabloid allegations he cheated on his wife of less than a year with a stripper he met while on location in Atlanta.
