One Direction have released an acoustic video for new single One Thing, and it's all dark and moody and SEXY.

Niall surrenders guitar duties to some bored looking bloke in headphones, and there are lots of lovely close-ups of the boys closing their eyes, scrunching up their faces and getting all involved.

They've finished filming the video in London, so hopefully that should be with us pretty soon too.
