One Direction have donned onesies and indulged in hand-painting in an advert for OnePiece.

The lads have appeared in a fun-filled video for the onesie company as they paint each other whilst wearing the company's products.

It seems they are promoting a new Hands range for OnePiece and the clip has proved a hit online.

The quintet can be seen slapping each other's bottoms with hand-paint and donning lipstick as they graffiti each other's clothes.

The 'Take Me Home' stars have had something of an affinity with onesie style garments for some time now, with the quintet snapped together whilst on the X Factor in 2010 wearing five different onesies.

As previously reported, One Direction singer Niall Horan has revealed that he will be helping shoot the band's first ever film, which is due out in August.
