Harry Styles has treated One Direction fans to some topless dancing.

The singer posed for the video camera over the weekend half-naked as he busted some moves to Kim Wilde's 1981 track 'Kids in America'.

Bandmate Zayn Malik can also be seen singing along as the group chill out backstage.

The clip was posted on One Direction's official Instagram account, with a video of Liam Payne dancing - with clothes on - also uploaded.

The boyband meanwhile are currently ploughing through the Australia and New Zealand leg of their Take Me Home tour.

Next up for the lads is a date at the Rod Laver Arena in Melboune on October 2.
