What's going on with Sarah Harding's ever-changing look?

Celebrities changing their appearance from time to time isn’t unusual.

But Girls Aloud star Sarah Harding‘s taken things to a whole new level – so much so we’re barely able to keep up.

But at least now we know why.

A close pal of the 29-year-old singer – who’s spent many a night out with her – says: ‘Sarah‘s always saying that everyone thinks Cheryl Cole‘s the best looking one in the band and she gets quite upset that all the attention’s always on her.

‘She wants people to think she’s just as attractive as Cheryl.’

Sarah‘s been through so many different looks: long hair, short hair, curly, straight, blonde… before recently settling on brunette – just like Cheryl.

Her pal adds: ‘I think she believes that if she looks more like Cheryl she can emulate her success as well.

‘Sarah‘s always had a complex about her looks and sadly Cheryl‘s superstar status only seems to have made it worse.’
