Britney Spears has teased her ''dirty'' and ''flirty'' new music video on Twitter.

The singer shared a sexy snapshot from the her first day of the video shoot for comeback single 'Work Bitch', which shows her flaunting her abs in a gold bustier and elbow-high leather gloves.

She wrote, ''Hot day on set... ;) A little dirty, little flirty, danced my ASS off. Stoked for tomorrow!'' before adding, ''#WerkBitch''.

The blonde bombshell dropped further hints about the highly-anticipated video the next day, revealing it was being shot in the middle of the desert.

Britney posted: ''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 former 'X Factor' USA judge was clearly feeling the effects of the sun, since she looked a little pink in the next picture she uploaded of her wearing nothing but a blue bikini.

The dancefloor track is thought to sample drag queen RuPaul's 1992 hit 'Supermodel (You Better Work)' after producer Jean Baptiste teased the lyrics on his Facebook page last week.

He wrote: ''To those who keep asking me and are too impatient to wait for the artist to deliver the single, here go some teaser lyrics.

'''Work, turn to the left, work, now turn to the right, work, sachey chantey...' (Rupaul voice).''
