Britney Spears brings forward song release after leak

Britney Spears was forced to bump up the radio release of her comeback single on Sunday (15Sep13) after a low-quality version of the song leaked online.

The Toxic hitmaker had been gearing up to premiere Work B**ch, a collaboration with will.i.am and songwriter Otto Knows, on Monday evening (16Sep13), but her plans were ruined after discovering it had already surfaced on the internet over the weekend (14-15Sep13).

In a Twitter.com post on Sunday, Spears wrote, "Woke up today and saw that a low quality version of Work B**ch had leaked... iamwill OttoKnows and I worked SOOO hard on this song! Can't wait for you all to hear it like you're supposed to..."

As a result of the leak, Spears' track made its big radio debut on Sunday afternoon.

Work B**ch had already hit headlines before it was even released - Swedish DJ Sebastian Ingrosso was forced to speak out to distance himself from the tune after he was listed as a songwriter on a lyric sheet Spears posted online on Wednesday (11Sep13).

Ingrosso insisted it was not his work on the track - he had simply passed along a song created by his artist Knows to the Black Eyed Peas frontman to use for Spears' new project.
