Tulisa Contostavlos London – Maria Tibrani Our new favorite X Factor Judge and singer Tulisa Contostavlos celebrated turning 23 yesterday at a star-studded night out at Movida nightclub in London. Known more for her street-style than elegant chic, Tulisa surprised us as she wore a beautiful body-hugging pink bandage dress which showed off her curves. The singer seemed very excited about her party, as she wrote on her Twitter page:  “Can’t wait for my birthday party tonight @MOVIDALONDON! Woop woop its Party time.”  And later on tweeted: “Just got the most amazing dress as a gift! So I\'ve decided to change lol @MOVIDALONDON we ready to party?! Let\'s gooooooo!” Not only did Tulisa look fabulous, but she arrived to the club in an equally fabulous ride – a red Mercedes SLS car, ready to mingle with friends and party. Attending the party were of course her band mates ‘Dappy’ and ‘Faze’ waiting outside for her. Other guests included The Wanted’s Tom Parker and Sugababes star Jade Ewen, who was wearing skinny black leather leggings. The star is currently preparing for the 8th season of X Factor. However, rumor has it that ex X Factor judge Cheryl Cole may be returning to the show as mentor during the judges\' house stage of the competition.
