Picture: Tulisa Contostavlos and her X Factor judges birthday cake!

X Factor 2011 judges

It's The new X Factor judges as you've never seen them before: immortalised as an amazingly detailed cake to celebrate Tulisa Contostavlos' 23rd birthday yesterday. The N-Dubz sar recieved the sweet present from her fellow X Factor judges as she sat on the panel during yesterday's Liverpool auditions.

This sneaky snap shows the cake - featuring X Factor judges Tulisa, Kelly Rowland, Gary Barlow and Louis Walsh behind the desk at the auditions - with their real life counterparts right behind.

And fresh in from the states, Kelly Rowland couldn't wait to tuck into the tasty treat, saying: "Happy birthday pudding y'all!"

But this was just one of Tulisa's gifts from her new X Factor pals, The joking judges also hired a hunky servant for the day to carry out the singer's very demand!
