Britney Spears stars in new Candie's ads

London, (ANI): Britney Spears has starred in the latest adverts for American fashion brand Candie"s. And the pop-star with a troubled past looks slim and radiant in the pics for the campaign.

However, a short time later, the 28-year-old pop princess appeared tired and podgy, with greasy unwashed hair, while out on a shopping trip in Beverly Hills, California.

Recently, fellow songstress Ke$ha, 23, blasted Britney on her new single Styrofoam, singing: “In 10 years, Britney Spears‚ Britney who?"

“She looked a bit tired but bear in mind she"s a young mum juggling parenting and a showbiz career. Cut the girl some slack!" the Daily Star quoted a Britney fan as saying.
