Zayn Malik and his bandmates reveal their new video ahead of its scheduled release

One Direction took to the stage to perform to an excited crowd at Camden's iTunes Festival yesterday and the boys also gave fans who missed out on tickets an unexpected treat.

After a poor quality version of 1D's new video for single Live While We're Young was leaked online, the release was moved forward and the video popped up on their Vevo page last night.

Delighted One Directioners took to Twitter to voice their appreciation, including Liam Payne's girlfriend Danielle Peazer. 

'I love #LWWY, congrats to @onedirection. But to the mean person who leaked it before it was officially released...karma will come and get u,' Tweeted Danielle, 24.

Live While We're Young is the debut single from the band's second album Take Me Home.

It's already guaranteed to be a surefire hit after becoming the most pre-ordered single ever to be released in the UK.
