On Wednesday night, Kate Middleton and sister Pippa repaired to Chelsea’s upmarket nightclub Raffles for an evening with a gang of City traders.

Kate is reported as saying, “I’m having a great time, I am drinking shots and I’m dancing with my sister and having fun.”

She was said to have knocked back shots of white rum and liqueurs made with rhubarb and apple, chased down with beer. She apparently ended up on her knees during a wild dance with Wiltshire-based fund manager Alex Boyd.

An onlooker said, “Kate was having a whale of a time, she seemed like a free spirit. She spent the whole night dancing with a group of male friends. She wasn’t just dancing but she was also knocking back strong shots and beers with them too. Kate seemed to be having a good time, at one point she was dancing with a friend to the Pussycat Dolls, she was telling them that they were her favourite band.”

Kate and Pippa left at 3am, slipping out of the club’s back door to avoid waiting cameramen. Probably just as well by the sound of it. It was said she walked home unescorted.

But was that wise? Walking home unescorted at 3am in London is really asking for trouble. Prince William really does need to get his girlfriend some protection now, especially if she’s going to walk on the wild side.
