Robbie Williams is to headline a charity concert for wounded servicemen and women at Twickenham Stadium.
More than 60,000 fans and troops are expected to attend the concert on Sunday, September 12.
Other acts confirmed today include Plan B, The Saturdays, James Blunt and Alexandra Burke, along with comedians Jack Dee, Michael McIntyre and Jason Manford, and entertainer Bruce Forsyth.
Proceeds will go to the Help For Heroes charity, which raises funds for wounded service personnel and their families.
Williams, who recently announced his return to Take That, said he was "honoured" to be asked to take part.
He said: “I am honoured to be a part of this show and to help draw attention to the amazing job done by our servicemen and women throughout the world.
"Their dedication to our country is phenomenal and we are all so proud of them."
Some 150 personnel injured in combat will attend the show free of charge.
Members of the public are being given the chance to purchase 1,000 extra tickets for other servicemen through the Tickets For Troops charity - ticketsfortroops.org.uk.
Bryn Parry, chief executive of Help for Heroes, said: “Music and humour can reach and lift those in the darkest of places, making life worth living and helping in recovery.
"Our boys and girls, both those operating in the remote patrol bases and those recovering from life changing injuries, will hear this concert and know that they are in the forefront of our minds. They are not forgotten, wherever they are.”
Richard Knight, Stadium director, said the concert would be a "fitting tribute" to hero troops.
Tickets for the gig, which will be shown on BBC One, go on general sale at 9am tomorrow at livenation.co.uk.
