Girls AloudIt seems like the chicks from Girls Aloud are doing it for themselves these days.

First it was Nadine Coyle and her restaurant business...

Then Cheryl Cole collaborated with Will.i.am, and most recently Nicola Roberts launched her own make-up range.

But who's flying the pop nest next?

Well, seems it's Sarah Harding, who's begun work on her first solo project.

She's recorded a track with nu-rave group the Filthy Dukes on the soundtrack of a new flick, Wild Child.

This could be the perfect dive into a solo career for Sarah - dontcha think?

A source told the Daily Mirror: "It is a really exciting project for Sarah to be involved with.

"She was chuffed to be approached and recognised as a singer in her own right.

"It's a pretty cool album with some big names featured on it including Rihanna, Robbie Williams and Nelly Furtado, so it promises to be a springboard for other things.

"Sarah's always maintained that she loves Girls Aloud and has no desire for the band to split - but that doesn't mean she's not willing to branch out."
