Mel B Behaves Badly!

Mel B stunned partygoers with her drunken raunchy behaviour.

The former Spice Girls star attracted attention at London’s Mayfair hotel on Tuesday by drinking several large glasses of red wine. She even shocked her husband Stephen Belafonte by performing an X-rated dance routine for him.

“She was absolutely drunk. Nobody knew where to look as her sexy behavior got seedier and seedier,” a source said.

Mel couldn’t keep her hands off her spouse and she passionately kissed him and grabbed his butt several times during the evening.

Despite her wild night, 34-year-old Mel — who was also pictured kissing the hotel’s manager — appeared fresh faced Wednesday when she jumped out of a giant birthday cake to celebrate underwear brand Ultimo’s 10th birthday.

Mel –who fronts advertising campaigns for the company — donned a red and black corset and happily signed autographs for fans at London’s flagship Debenhams store.

She was hailed as “a great ambassador” by Ultimo creator Michelle Mone.

“I think Mel B is a gorgeous looking woman with an amazing looking figure. She has got a figure to die for,” Michelle said.

“I think it’s her personality as well – she is just so warm and she says it as it is. Ultimo is about real women and she is a real woman and that’s what I like about her.”
