Christina Marie Wickens is the new favourite to win The Voice 2014.
The 20-year-old from Bristol - coached by Kaiser Chiefs frontman Ricky Wilson - has overtaken 54-year-old Sally Barker in the running, according to bookmakers William Hill.
Christina has odds of 11/8, while former favourite Sally - mentored by Sir Tom Jones, whose act won the first series of the BBC talent show in 2012 - lags behind with odds of 13/8.
New coach Kylie Minogue's finalist Jamie Johnson is third with odds of 4/1 and Will.i.am's protege Jermain Jackman has the least chance of winning at 5/1.
The live final on Saturday night will see each finalist perform a song of their choice, as well as a duet with their celebrity mentor.
The contestant with the lowest number of votes will be eliminated and the three remaining contestants will perform once again.
Aspiring politician Jermain, 19, has revealed he will be singing Miley Cyrus' Wrecking Ball for his first solo song. He said: "This song really meant a lot to me, it was the first time I sang publicly, as I used to be a shower singer."
Coaches Tom, Kylie, Will.i.am and Ricky will open the show with a special group performance.
Kylie is yet to confirm whether she will return to the show next year as filming for the auditions clashes with her new tour. Ricky has said he will not return without her.
