New X Factor judge Tulisa Contostavlos was partying it up at T4 On The Beach yesterday alongside Xtra Factor host Olly Murs and former contestants Cher Lloyd and JLS. Closing the show yesterday evening, Tulisa and her N-Dubz bandmates Fazer and Dappy showed this year's hopefuls how it's done.
Singing live unlike certain former X Factor judges, Tulisa and the group got the crowd going with their new single 'Best Behaviour' as well as old favourite 'Playing With Fire'.
Tulisa has already been tipped to perform her debut solo material on the live X Factor shows later this year.
