Tulisa parties with Chipmunk
The young star danced the night away with her friend, just like any party-loving young woman would.
She kept up her glamorous image for the party, deciding to opt for a very on-trend Little White Dress.
Lauren's co-stars Chloe Sims and Frankie Essex were there too and Tulisa managed to grab a picture with the Essex girls.
X Factor boy band JLS were there too and posed for a picture with Tulisa and the birthday boy.
It must have been a good night for Tulisa, who obviously drank enough to do some drunk tweets! We've all been there, right?
