A song from Dr Dre's much-anticipated new album 'Detox' has leaked online.

The seemingly unfinished track, entitled 'Under Pressure', features Jay-Z, and is thought to be the first single from the LP.

Dr Dre opens the song by alluding to fans' long wait for 'Detox', which will be the follow-up to his 1999 album, '2001'.

Jay-Z then raps about golfer Tiger Woods' recent personal troubles, saying: "I'm in this party/ I'm up to no good/ And I should be ducking these clubs, Tiger Woods."

In April, Dr Dre said he was hoping to release 'Under Pressure' “in the next two weeks or so”, but the song never arrived.

The rapper and producer added that he was looking to releasing the album this year.
