The pop singer shows a glimpse of her former glory with a series of racy outfits and seductive poses in the video for Circus, the second single off her album by the same name.
The extravagant production is set around the big top theme, with a scantily clad Britney playing ringmaster to back-up dancers, elephants and lions.
Roll up, roll up: Britney Spears strips down to a lacy bra in the video for her latest single Circus
While Britney looks back to her best in the carefully edited clip, her comeback has otherwise been a little shaky.
Expectations were high for her appearance on Saturday's X Factor show, where she performed hit single Womanizer for the studio audience.
However she failed to sing live and she appeared nervous throughout the lackluster dance routine.
There was a sense of deja vu a few days later when Miss Spears performed songs from her new album in front of millions of viewers on U.S. TV show Good Morning America.
She again lip-synched her way through the two track performance.
Despite all this, Britney's album is on track to scoop the coveted number one spot on the album charts next with.
While her fans are eager to see Britney back in fine form, so to is her ex husband Kevin Federline, who yesterday broke his silence over the pop star.
He told American magazine People: 'Just because I'm not in love with her doesn't mean that I don't love her. I'm definitely rooting for her.
'There's nothing more that I want than for her to be in the best health and doing what she loves to do.'
The dancer turned rapper says Britney, with whom he has two children, is slowly getting her life back on track.
'Oh, man, it's totally turning around,' said Kevin.
'It works out that [the kids] get to see her. There's structure over there, there's structure at my house.
'We're trying to keep the same type of schedule. It doesn't have to be completely perfect, but the foundation is there.'
