Sarah Harding turns 30 today and after the year that she has had, she is in desperate need of something to celebrate.

The British singer and Girls Aloud star hits the milestone age after a rollercoaster year which has included splitting with fiancé, Tom Crane and checking herself into rehab.

Serial party goer, Harding seemed to be getting her hectic life back on track until she separated from her DJ fiancé Crane in September after he reportedly got tired of her wild antics and constant partying.

She checked herself in a rehab centre on 11 Oct, to combat her depression and alcohol addiction as she apparently hit rock bottom following the split.

The singer appeared relaxed and refreshed as she took her first steps back to normality this week following her month long stint.

Aside from being in one of the most successful UK girl groups ever, Harding as also had a stint in acting and model. She starred in the 'St. Trinian's' film series as Roxy and was formerly the face of underwear brand Ultimo.

Here's hoping that she can rally round her Girls aloud for a fitting celebration as bandmate Kimberley Walsh also celebrates her 30th birthday on Sunday.

Let's have a look at Sarah's life in pictures...
