The N-Dubz singer partied in true celeb style.
Tulisa was joined by her N-Dubz pals, The Wanted and Sugababe Jade Ewen for her 23rd celebrations in London.
"Cant wait for my birthday party tonight @MOVIDALONDON! Woop woop its Party time," the X Factor judge tweeted before the bash.
"Just got the most amazing dress as a gift! So I've decided to change lol @MOVIDALONDON we ready to party?! Let's gooooooo x" (sic)
Tulisa, wearing a body-con pale pink dress with killer heels, arrived in a red Mercedes and was presented with 20 bottles of posh champers and a personalised chocolate cake.
But after a night of partying with her musical mates, the next day was all about chilling out.
"3 things......roast dinner, telly, SLEEP!" Tulisa tweeted. "Nothing more nothing less."
