Coldplay, Leona Lewis, Michael Buble, JLS and One Direction will perform at the X Factor final at Wembley Arena.
The live finals will this year take place at Wembley Arena on December 10-11.
Coldplay frontman Chris Martin said: "We're all big X Factor fans so we're very excited to play live on the show."
Meanwhile, 2006 champion Lewis previously revealed that she would perform, as she releases a three-track EP later this month.
JLS and One Direction, who feature on the X Factor charity single, will also take to the stage.
Show judge Gary Barlow added: "This is the biggest final The X Factor has ever done. Being at Wembley Arena for the first time and in front of 10,000 people with Coldplay performing, I can't wait - it's going be an amazing night."
It has not been confirmed if any of the performs will duet with the X Factor finalists.
