Princess Eugenie has only recently become old enough to get into clubs, and she is certainly making the most of it. She was having a ball last night at the £2.5 million re-launch of Movida nightclub.

Party Princess: Eugenie at the re-launch

An onlooker said: "She was sitting with a male chum and a group of other friends. They were all having a great time, dancing and laughing."

But the fun came to an abrupt halt when Eugenie tried to get herself a drink. Our spy continued: "Eugenie and her chum were trying to open a bottle of champagne together, but obviously don't have too much experience - the bottle exploded, covering their friends and other clubbers in bubbly.

"Some people looked really angry, and when a bouncer went to tell them not to do it again, Eugenie hid behind her friend like she was still at school. No-one minded too much, and they were soon dancing again."

Eugenie is a regular weeknight clubber - usually at Boujis, Kitts and Whisky Mist - definitely giving her the title of the party princess.

However, despite being sixth in line to the throne, Eugenie hardly puts on any airs and graces.

She was dancing with friends outside the VIP area while Paris Hilton demanded her own VIP spot and was surrounded by four bodyguards. We know Eugenie must have a bodyguard somewhere, but he was being more discreet than Paris's people - naturally!
