New X Factor judge Tulisa Contostavlos is reportedly 'thrilled' with her role on the show - despite it leaving her with less time for fun! The N-Dubz star however made up for her tough schedule at her 23rd birthday party at the weekend, filling up with "booze, booze and more booze".
The new X Factor babe celebrated turning 23 in style as she and her celeb friends - which included her N-Dubz bandmates and The Wanted - got through 20 bottles of champagne in a matter of hours on Saturday night at London’s Movida club.
An insider source said: "Tulisa was definitely ready for some fun and made sure the alcohol was flowing to get the party going.
"She arrived in a red Mercedes straight from performing at Guilfest with N- Dubz to party with her bandmates, boyband The Wanted, and Sugababe Jade Ewen.
"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."
Speaking to the Daily Star, the source continued: "Tulisa is thrilled she gets to do The X Factor as well as continue with N-Dubz, but the heavy schedule has left her worn out with less time for fun."
They added: "For her birthday she definitely put that right by having such a great night."
Tulisa will make her debut on The X Factor alongside fellow new judges Kelly Rowland and Gary Barlow when the show returns next month.
