One Direction are to headline BBC Radio 1's Teen Awards this year.
The What Makes You Beautiful stars will be joined by Conor Maynard, Taylor Swift and Little Mix on the bill for the show to be staged on October 7.
The awards, which take place at Wembley Arena, will be hosted by presenter Nick 'Grimmy' Grimshaw - who takes over from Chris Moyles as breakfast presenter next month - and celebrate inspirational teenagers.
One Direction star Niall Horan said: "It was so much fun last year and it's a great line-up. It's always good to be on a great bill."
Listeners are invited to nominate teenagers to receive three Teen Hero Awards to recognise their exceptional achievements.
Grimmy said the awards bash was "one of the most fun events of the year".
He added: "This year's going to be bigger and better than ever - as well as celebrating inspirational teenagers, one of the biggest bands in the world, One Direction, will be playing."
There will also be awards for stars from the worlds of music, entertainment and sport, with a panel of celebrities, including Radio 1 DJs, alongside experts choosing the teen hero winners.
Can't Say No star Conor said: "To be asked to perform at something that's also for an amazing cause feels so exciting. I think the feeling to be nominated for something like that would be amazing."
Tickets go on sale on September 22 with more details at www.bbc.co.uk/radio1.
