Luann Lee has claimed that Mel B burst in on her in a disabled toilet and gave her a big, passionate smooch on the lips.

The ex-Playboy model 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.

“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.

“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.”

Unfortunately for Mel B, she had to be quick because her HUSBAND was waiting patiently outside!

What the heck?!

We’d say Lee will REALLY see why they call her Scary Spice when Mel B finds out what she’s been saying about her!
