Jessie J and boyband JLS are among the big names secured by Take That's Gary Barlow for the Queen's Diamond Jubilee concert.
The event is due to take place on June 4 in front of Buckingham Palace, with Ed Sheeran, Sir Elton John, Sir Paul McCartney, Dame Shirley Bassey and Jools Holland also among those due to perform.
Alfie Boe, Annie Lennox, Cliff Richard, Madness and Lang Lang complete the bill as it currently stands, but more performers are due to be added in due course.
Barlow said in a statement: "The Diamond Jubilee concert will celebrate the 60 years of The Queen's reign with an amazing lineup of world-class artists coming together to play at one of the biggest and most exciting live music shows in recent years.
"With Buckingham Palace as a backdrop, it's going to be a fantastic event which transcends multiple decades of music. It'll be a great, unique, experience for the thousands attending, watching on TV and listening on Radio. I can't wait!"
10,000 lucky members of the public will be selected to recieve free tickets via a national ballot. Applications, which are currently being accepted on the BBC website, close on March 2.
