One Direction's Harry Styles has confirmed that the group have finished working on their third music video. 

The teen sensations recently filmed a video for their forthcoming new single 'One Thing' and the floppy-haired heartthrob took to social networking site Twitter earlier today (November 29) to thank fans for their involvement:

"Big thanks to everyone who got involved in our video yesterday!! It was fun, and hopefully you'll like it. Video 3...done!"

The stars shot some scenes for the new offering yesterday in London's Trafalgar Square after putting out an open call for people to turn up and were photographed riding around in an open top red bus.
