Britney Spears has debuted her new single "Work Bitch."
The song was expected to premiere on radio on Monday, but Britney took to Twitter Sunday morning with the official audio, writing that a low quality version of it had leaked online.
After releasing the official version, Team Britney announced that the song will become available to purchase on iTunes starting at midnight.
The much-anticipated new single was supposed to be timed with the star's appearance on Tuesday's "Good Morning America."
A video, which Britney tweeted about shooting last week, is expected out soon as well.
