The World's First Supermodel Janice Dickinson revealed to the News of the World that she swings both ways.

In the interview, Janice reveals that she had sex with Mich Jagger's ex-girlfriend, Pia, when she was supposed to be comforting her during the break-up.

"One thing led to another and before long I was crossing the line," Dickinson said.

"Pia and I ended up spending an awesome evening together—having the best sex ever. Maybe it was her grief at losing one of the greatest rock guitarists in history.

"Or maybe she was just horny.

"Whatever. As girl-on-girl interludes go, it was hot, steamy and wild."

BUT that isn't the only lady Miz Dickinson claims to have banged.

Janice also claims to have ended up in bed with actress Kelly LeBrock and singer Grace Jones and a whole list of Hollywood men too including Sylvester Stallone, Jack Nicholson, and Bruce Willis.

The kicker:  Janice says he perfers women to men.

"You get to have sex, swap shoes and that toilet seat stays down at all times," she explained.

Dickinson is currently dating cameraman Tommy Fry.
