Mel B accidentally exposed herself to Kate Moss and Naomi Campbell.

The Spice Girls singer was chatting to bandmate Mel C as she removed the tight-fitting catsuit she wore to perform at the London Olympics closing ceremony and completely naked when the supermodels - who were also part of the spectacular event - walked into the bathroom where she was changing.

Mel told the Daily Mirror newspaper: ''Me and Mel C were in the bathroom. To get my costume off you had to go fully naked. So I'm sitting there on the loo, naked with Mel C and then in walked Kate Moss and Naomi Campbell. Melanie was like, 'You couldn't even write that.'

''I won't tell you what happened next but it was lovely.''

Meanwhile, Mel C says she now has a ''sisterly'' relationship with her bandmates, Mel, Geri Halliwell, Emma Bunton and Victoria Beckham, but admits they didn't always get along all of the time.

She told Woman magazine: ''We had our moments. But there are no bitches in the band. Me and Melanie B had a fight once. A proper one. I think Geri got hit splitting us up.

''It's a sisterly relationship because we've experienced something very unique together. We do make an effort to get us and the kids together.''
