Bronzed and slim Britney prepares for a comeback that will 'blow fans away'

But having taken some time out to focus on herself and her sons, it seems the singer could be capable of making the astounding comeback her industry insiders have promised.

Brand new Britney: The star looked slim and tanned in Beverly Hills

Sporting her trademark long beach-blonde hair, a slimline Britney stepped out of Beverly Hills BV2 hair salon where she had spent a reported four hours preparing for her upcoming appearance on Madonna's tour.

In a knee-length, high-necked sundress and oversized sunglasses the Baby One More Time singer looked every inch the star who once dominated the charts.

And if insiders are to be believed Britney will be regaining her Princess of Pop moniker very soon.

High spirits: The singer smiled at onlookers and looked genuinely happy as she prepared for her next comeback

The 26-year-old star is currently making a video that will be screened on the Queen of Pop's upcoming 'Sweet and Sticky' performances.

However, fans should expect a changed Britney in her next venture back into music.

A Spears insider said to E! News: 'The video will be very deep. You’ve never seen Britney like this before. It will blow your mind.'

Although filming has currently halted due to technical glitches, the video will feature the star performing in an elevator.

Madonna's publicist Liz Rosenburg has confirmed Britney is being filmed for the 50-year-old's tour but refused to reveal more.

She said: 'There is footage being shot of Britney some time this week in conjunction with Madonna’s upcoming tour. That is all the information I have available. The rest is a secret.'
