You've got to hand it to Britney - she's got determination in bucket loads.
The popstar looked toned, tanned and on top form in the video for her new single, Hold It Against Me.
Wearing a crop top - which reveals her flat tummy - and sporting cascading curls, she looks in her element surrounded by topless male dancers.
However, the singer has had to deny using a body double to complete some her choreography for her.
Her spokesman told TMZ: "These accusations could not be further from the truth.
"Fans will immediately see how inaccurate these claims are once they see the video."
And the video's director, Akerlund, said that Britney had been 'great throughout the entire process and gave it her all,' adding,'this video is gonna be f***ing awesome. It's all Britney."
Hold It Against Me is the first track to be released from her new album, Femme Fatale, which is out on 29 March.
The video will premiere on mtv.com on 17 February.
