Britney Spears is working on hard on her musical reinvention, according to proucer Rodney Jerkins.

The troubled star has had a rocky year, which she has spent fighting an ongoing custody battle with ex-husband Kevin Federline.

But Grammy-winning producer Jerkins - who produced remixes for Spears' tracks Overprotected and I Love Rock 'n' Roll - insists her new music will resurrect her troubled public image, according to People.

He says, "I'm trying some new things (with Spears) I've always worked with Britney and I love working with her.

"I'm try to reinvent her and reinvent myself with her project. It's about to be her time again."

Can she re-capture some of her hottest moments?
