Britney Spears is back to where she started from. The "Hit Me Baby" songstress has posted a sexy picture of herself on her Instagram account that flaunts her slim and well toned body in a blue coloured sexy bikini. The singer clicked the picture in what appears to be her dressing room.

"Gonna get my tan on in the desert in between shots on the #WorkBitch set today. It's HOT out here people!!!! #desert #heatwave," the 31-year-old singer wrote as she posted her pictures.

The picture shows Britney standing tall in her bikini with an absolutely flat stomach and envious curves. The mother-of-two teamed up the bikini with a pair of greyish glittery pumps and tousled blond tresses falling on her face above her shoulders.

The day before, she posted a photo of herself in a black and golden bra. Britney captured the screen shot of the video camera's screen.

The singer herself confirmed to her fans that she is shooting for the music video of the single "Work Bitch" and posted the picture [SEE PICTURES] to her Instagram on Saturday and told fans that she had 'danced her ass off' during filming.

"Hot day on set... ;) A little dirty, little flirty, danced my ASS off. Stoked for tomorrow!" she said then.
