Robbie Williams is being tipped to sing with Che Chesterman on The X Factor 2015 final this weekend.
The performer, who previously duetted with Olly Murs, has emerged as Betway’s 5/2 favourite to duet with Che at this weekend’s X Factor live finals from Wembley Arena.
Swing-fan Che could instead opt to collaborate with Michael Buble (11/4), who is yet to make an appearance in this series, or even presenter Olly Murs (5/1).
Whilst Che’s performance is less predictable, the online bookmaker makes Leona Lewis (1/20) and Cheryl Fernandez-Versini (1/10) long odds-on favourites to perform with Louisa Johnson and Reggie ‘N’ Bollie, respectively.
However that's despite the fact that Rita has already confirmed she will be singing with Louisa, although the pair have yet to pick a song.
Betway’s Alan Alger, said: “There have been mutterings of Stevie Wonder or Sam Smith coming in to collaborate with Che Chesterman, but the market support has been with Robbie Williams, Michael Buble and Olly Murs.
“The weight of bets we’ve had for Leona Lewis to partner Louisa Johnson has been significant. Lewis has confirmed she will be performing on the show and we think it’s nailed on that will come in the form of a duet with Louisa.”
Other names confirmed for the weekend's live shows are Coldplay and One Direction.
The X Factor 2015 final airs this Saturday and Sunday night live from the SSE Arena, Wembley.
