X Factor's Tulisa Contostavlos celebrates 23rd in London

X Factor judge Tulisa Contostavlos flaunted her enviable figure and sank champagne in style at her 23rd birthday in London this weekend.

The judge and N Dubz singer wowed her celebrity guests as she arrived at one of the glitzy party venues London is famous for.

Arriving in a bright red Mercedes, the youngster “turned heads” according to the Mail Online, and was wearing a tightly bound rose-coloured dress with a pair of black and pink snakeskin heals.

Fellow bandmates Dappy and Fazer were in attendance, as well as the latest boyband sensation, The Wanted and Sugababe Jade Ewen.

So-called “spies” of the Daily Star also revealed that Tulisa was in the party spirit, with 20 bottles of champagne going down within hours.

“Tulisa was definitely ready for some fun and made sure the alcohol was flowing to get the party going,” they said. “She spent hours dancing to her favourite songs before the club stopped the music at 1am to play Stevie Wonder’s Happy Birthday whilst presenting her with a big chocolate birthday cake.”

The insider added that Tulisa is “thrilled” about her judging role in the X Factor but said that a punishing work schedule has left her with less time for fun: “For her birthday she definitely put that right by having such a great night,” they said.

Meanwhile, the paper’s sister publication, the Daily Star Sunday, claimed yesterday that Cheryl Cole could be making a return to the X Factor to help Tulisa as a mentor during the judges’ house stage of the competition.

A source told the paper: “Cheryl has already been offered the chance to come back and mentor the contestants during the live rounds.

“There’s also talk she could perform with one of the contestants for the grand final. Cheryl basically has any option to return she wants, apart from as a judge.”
