Britney Spears and Sir Elton John' s new single has leaded online ahead of its release.
A snippet from the pair's duet, Hold Me Closer - a reworking of Sir Elton's 1971 hit Tiny Dancer - was shared across social media on Thursday night, with fresh Britney vocals heard for the first time in six years.
Fans were divided on whether to listen to the unauthorised audio, after it was rumoured the mum-of-two's big musical comeback was due to be officially released within a matter of hours.
