The girls shared a number of party snaps on their Twitter pages throughout the evening, which showed them looking very pretty, drinking cocktails, cuddling and dancing!
But Cheryl Cole has revealed that she hasn’t always wanted to share everything with her bandmates.
The singer told Fabulous magazine that she didn’t want to see her bandmates before her performance at the O2 in London.
It seems she was too worried about performing to even think about inviting her friends backstage for a catch up.
Apparently Chez didn’t want a fuss backstage, including not knowing which celebrities were in the audience and where her Girls Aloud bandmates were sitting.
