Cameron makes cameo in 1D video
One Direction were joined by David Cameron as they made the music video for the official Red Nose Day song.
The Prime Minister makes a cameo in the boy band's new video for their Comic Relief charity single One Way Or Another (Teenage Kicks), which they filmed outside 10 Downing Street.
"Enjoyed my cameo in @onedirection's vid for @comicrelief charity single. Glad to help with the filming location!#1DRND," he tweeted.
In order to save money for Comic Relief, the band - Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - decided to film the video themselves during trips around the world whilst they were on tour.
It includes scenes filmed on the road in New York, Japan and London as well as Africa, when they visited projects supported by money raised through Red Nose Day earlier this year.
One Direction - who will not receive any payment from the single - will perform the track, which is a mash-up of Blondie and The Undertones' 1978 hits, at the Brits for the first time on February 20.
The song is now available to download and buy, in time for Red Nose Day on March 15.
