Will.i.am has unleashed the video for his new Britney Spears collaboration.

The Voice UK coach has teamed up with the pop princess for the single 'Shout & Scream', which will be taken from his forthcoming new album '#willpower'.

The highly-anticipated song was unfortunately leaked online before its official release but the video has now been unveiled.

It was originally screened on Wednesday's (November 28) episode of X Factor USA, on which Spears works as a judge.

The video sees the duo sing the song in front of a variety of backdrops, with will.i.am at one point wearing a crown hat with the word 'king' on top.
