X Factor judge and N-Dubz singer Tulisa Contostavlos celebrated her birthday in style on Saturday night with champagne and chocolate cake.

The singer headed out to London’s Movida nightclub with friends and her N-Dubz bandmates as she turned 23.

Before she left for the evening, she tweeted: “Cant wait for my birthday party tonight @MOVIDALONDON! Woop woop its Party time.”

Contostavlos arrived in a red Mercedes, straight from a performance at Guilfest, and partied until 2.30am. At 1am, the DJ played Stevie Wonder’s Happy Birthday.

Pop band The Wanted also showed up to the club, where Tulisa was presented with a giant personalised chocolate cake and 20 bottles of Dom Perignon Champagne.

A source told The Mirror: “Tulisa has been working really hard over the last few weeks, so jumped at this chance to let her hair down with her mates.

“She was dancing for hours to all her favourite songs and throwing in a few ironic gangster rap style moves.

“[Bandmates] Dappy and Fazer were trying to ply her with champagne and shots but she was being pretty sensible.”
