Coldplay and Michael Buble have been lined up to appear in the 'X Factor' final.
While it is not yet known who will be battling it out in the hope of being crowned winner of the ITV1 series, it is thought Irish teen Janet Devlin's voice would be most suited to the 'Fix You' hitmakers and the Canadian crooner could complement Marcus Collins' style.
An insider told the Daily Star newspaper: "There isn't anyone left in the show who would suit Coldplay's music apart from Janet.
"She wowed everyone when she sang 'Fix You'. It shows how confident everyone is that Janet will make the final."
Although the third act has not yet been confirmed, if girl band Little Mix reach the two-part final on December 10 and 11 they are keen to sing alongside 'Price Tag' hitmaker Jessie J, who helped their mentor Tulisa Contostavlos select her finalists at the Judges' House stage of the competition.
Jesy Nelson said: "It would be so cool to duet with her in the final if we make it."
Despite Janet having potentially bagged a slot alongside Coldplay in the 'X Factor' final, she and fellow acts Misha B and Amelia Lily are said to feel "deserted" after mentor Kelly Rowland jetted off to Paris to promote her new single.
