Britney Spears' new single has leaked online.
The 31-year-old singer was left disappointed after a low quality version of her new track 'Work B**ch' emerged on YouTube on Sunday, but she has urged her fans to put off listening to the
song until the real thing is played on the radio today.
The song has since been officially released on YouTube.
Writing on her official Facebook page, she said: "Woke up today and saw that a low quality version of Work Bitch had leaked. will.i.am, Otto Knows, and I worked SOOO hard on this song! Can't wait for you all to hear it like you're supposed to... (sic)."
The blonde beauty has been teasing fans for weeks about her comeback single and even shared a sexy snapshot from her music video, which shows her flaunting her tight abs in a gold bustier and elbow-high leather gloves.
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 two weeks ago.
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)."
