Adam Lambert and Queen will perform on The X Factor 2014 live shows later this year, it's been confirmed.
The two acts will take to the stage together in the results show after Dermot O'Leary confirmed the rumours of a performance in last night's performance show.
Other names rumoured to be set to singing on The X Factor this year include last year's champ Sam Bailey, former X Factor judges Nicole Scherzinger and Gary Barlow, with his Take That bandmates, as well as former finalists Ella Henderson and Olly Murs.
But Tulisa it's said - who has a new comeback single out later this year - has not been invited.
Meanwhile, even though the last live show of the series is still well over a month away, plans for the possible finalist duets are already being made.
While in recent years the judges have often sung with their acts it looks like that plan has been ditched.
The Daily Star on Sunday newspaper reports that Sam Smith and Ed Sheeran are both in talks with producers to sing with finalists on the final.
Ed, who previously performed on the live shows earlier this year, has said he's a big fan of Andrea Faustini who is the current favourite to win.
