Pop stars One Direction took their latest music video to new heights by filming the promo on top of London's iconic Tower Bridge.

The singers were photographed standing on the edge of the bridge wearing safety harnesses while shooting the video for a new single on Saturday (21Dec13).

They braced the cold, wet weather for the shoot 200-feet (61-metres) above the River Thames, and Liam Payne was spotted swinging from a beam, while Harry Styles was seen capturing the moment by taking pictures on his cell phone.
