Cheryl's birthday goes with a bang

Newly blonde star looked happy at her star-studded bash

Despite speculation that Cole was feeling down since being axed from the US X Factor, Cheryl Cole was on top form at her birthday party in London last night.

The star showed off her new asymmentrical, blonde hairdo, and truly let her hair down at the bash, held at London's Sanderson Hotel.

The Black-Eyed Peas, Kimberley Walsh and Nicola Roberts helped the 28th year old celebrate in style.

In attendance were also Matthew Cole, Cheryl's ex husband's Ashley's brother, and N-Dubz Tulisa Contostavlos, who is replacing Cheryl as UK X Factor judge.
