According to former Playboy model Luann Lee, she and the former Spice Girl had a sexual encounter in a disabled toilet whilst she was performing her Peep Show run in Las Vegas.
Speaking to The Sun on Sunday, Luann said: "It was very passionate and sensual. She’s like a man in that way - very assertive, very determined and very wanting. I can see why they call her Scary Spice."
“I went into the handicapped stall because it’s bigger and I wanted to put my purse down - and she just popped in with me. She said, ‘Do you mind?’ and came right in. Then she just threw me up against the wall and started kissing me.”

Is Victoria Beckham going to be joining Mel B at the judges houses?
She continued: “She was a good kisser. Her lips are very soft and full and she has a tender touch. It was maybe a five-minute kiss and after that she started going for other areas.”
Mel B has admitted to being with women in the past, and even told TV host Howard Stern that she enjoyed a five-year relationship with her close friend Christa Parker.
The X Factor judge said: "People call me lesbian, bisexual or heterosexual, but I know who's in my bed and that's it."
What do you think of Luann's claims?
