Robbie Williams is set to headline a huge charity gig in front of 60,000 people in London on September 12.

The concert is to help raise money for Help For Heroes, an organisation that supports wounded servicemen and women in the Armed Forces.

Other artists including Gary Barlow, JLS, Pixie Lott, Kasabian and Stereophonics are also in talks to perform at the concert, which has been put together with the help of The Who's Roger Daltrey.

Prince Harry, who has served on the frontline in Afghanistan, is thought to be attending the event.

The concert will take place in Twickenham and be broadcast by the BBC.
