Mel B
A former Playboy model claims she had a steamy encounter with Spice Girl Mel

A former Playboy model has claimed she had an intimate encounter with Spice Girl Mel B.

In an interview with The Sun, Luann Lee said that the X Factor judge followed her into a disabled toilet, where the two spent an hour together, kissing.

Lee, who met the X Factor judge in a hotel bar when she was starring in The Peep Show at the Planet Hollywood Hotel, said there was instant sexual chemistry between them.

Recalling the brief liaison, she said: "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."

The centrefold claimed that the singer's husband Stephen Belafonte was waiting outside the whole time.

Describing the encounter she 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.

"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."

The Playboy model, who is a mother-of-one, said that after about an hour a security guard came to check if they were OK, before asking them to leave.

Lee said she was keen to keep seeing Mel, but claims the singer's husband Stephen Belafonte 'got in the way' and was jealous of the relationship.

Last year Mel B revealed to shock jock Howard Stern that she had been in a five-year relationship with Christa Parker, who she met at an LA party.

Speaking about her sexuality, she said: "People call me lesbian, bisexual or heterosexual, but I know who's in my bed and that's it... I have a huge libido and a great sex life."

Earlier this year she was seen kissing and cuddling a female friend while they relaxed in their bikinis, alongside her husband Stephen Belafonte.

The star has been married to film producer Stephen since 2007 and the pair are parents to a little girl called Madison.

She is also mother to Angel, from a brief fling with Eddie Murphy and Phoenix Chi from her marriage to dance Jimmy Gulzar.

The singer returns to the UK, joining Cheryl Cole, Louis Walsh and Simon Cowell as the fourth judge on the X Factor.
