The hotly-anticipated guest performances for this year's X Factor live final have been announced - and it's a bit of a 'mixed bag' to say the least.
X Factor graduates One Direction will join rockers The Killers and veteran hit-maker Elton John on stage at Wembley Arena on 14 & 15 December.
BRITs Critics Choice Tom Odell and X Factor favourite and 'friend of the show' Katy Perry will also be performing.
Elton John is to join X Factor judge Gary Barlow for a world exclusive performance of their duet Face to Face, due for release in January 2014.
The Killers meanwhile, making their debut on the X Factor, will delight fans by performing two of their most infamous and beloved hits Mr Brightside and Human.
