One Direction treated their fans to a rendition of the Harlem Shake dance routine on Monday (April 1).

The dance, which sees its participants go wild after waiting still for a short period of time, has become an internet craze this year.

The One Direction lads decided to try it out on their fans whilst performing at London's O2 Arena.

The group got their drummer to build the beat as the quintet got ready to show off their wacky dance moves.

Whilst Niall Horan and Harry Styles went somewhat gung-ho, the other members, however, seemed a bit confused as to what to do.

Their fans predictably lapped it up, however, with one YouTube user commenting: "I don't know how many times I'm going to watch this over and over again."
