Justin Bieber has called upon his fans to pick the cover for his next single.

The Canadian hitmaker is due to release 'Boyfriend' on March 26 - but he's unsure what to use as the artwork.

He is giving fans the chance to choose between two covers - both sporting Bieber in a thoughtful pose, resplendent in a checkered shirt.

They are asked to tweet in hashtag form which cover they prefer. Watch Justin Bieber announce the release of 'Boyfriend' below:
