Britney Spears has proudly shown off her toned, tanned physique in the latest photos she's posted on Twitter.
The Piece of Me singer stripped down to a teal-coloured bikini and sky-high sparkly heels, and teased fans with snapshots from the set of her new video, for upcoming track Work B****.
"Gonna get my tan on in the desert in between shots on the #WorkB**** set today. It's HOT out here people!!!! #desert #heatwave," wrote Britney.

The 31-year-old singer, who has been putting in extra hours at the gym and at yoga classes, was clearly eager to show that her tough fitness regime had paid off.
She flaunted her enviable long legs and tousled blonde hair in one snapshot, and gave fans another sneak peek of the video in a second photo — this time of the singer posing in a gold and black cropped bralet, with matching black leather gloves.
The pop sensation has been on the video set for a couple of days now, and is clearly excited to be working on her latest clip and making her return to the stage.
"Hot day on set... ;) A little dirty, little flirty, danced my ASS off. Stoked for tomorrow!" she tweeted the day before.
Britney is due to reveal the track with a performance on Good Morning America on 17 September, ahead of its release.
