Niall Horan strips off for new One Direction Comic Relief music video starring Japanese girls, air hostesses and... David Cameron

Showers, Japanese girls and a rather awkward cameo by David Cameron - those teenage heartthrobs One Direction decided to make a rather different video for their latest single.
Instead of splashing thousands on a slick music video Harry Styles, Zayn Malik, Niall Horan, Liam Payne and Louis Tomlinson decided to film the One Way Or Another (Teenage Kicks) while on tour and donating the cash saved to Comic Relief.
The mash-up video of Blondie's One Way or Another and the Undertones' Teenage Kicks is introduced by heartthrob himself Harry and then follows the boys around the globe.

New York, London, Japan and Africa all feature in the video - but perhaps some of the boys may be a little bashful after the video goes online.
Zayn, 21, is seen welcoming the camera into his hotel room and pulling back the covers - an unfortunate scene as the tattooed singer was accused of cheating on his long-term girlfriend with an Australian stripper, apparently proven by a nude bed shot of the singer. 
Fans of blond Niall may be watching the video more than once as the What Makes You beautiful singer is seen taking a shower and in the bath.

Those cheeky boys even dance with an awkward-looking David Cameron and dance outside Number 10 - all in the name of charity.
The band were welcomed to Downing Street at the end of last year to shoot scenes for the Red Nose Day single, and according to the PM he 'enjoyed' his brief role.

On Sunday, Mr Cameron tweeted a picture of himself with the band, that read: 'Enjoyed my cameo in @onedirection's vid for @comicrelief charity single. Glad to help with the filming location!'

A government donation will cancel out the cost of VAT on the record, with a Downing Street spokeswoman adding that the government would also make 'a charitable donation that will be the equivalent of the VAT' by covering the cost of VAT on sales of the single from the overseas development budget.
