2U (The Scene Kings Remix) David Guetta feat. Justin Bieber
Beyonce's forthcoming album '4' has leaked online three weeks ahead of release.
The leak comes a day after new track 'Party' found its way online.
Hours later another song 'Countdown', which features a sample of Boyz II Men's 1991 hit 'Uhh Ahh', also emerged on the net before the entire album itself surfaced.
'4' is not due to be officially released until June 27th.
The day before (June 26th), Beyonce is due to headline the main stage at Glastonbury.
