Lydia Lucy has a "mad" duet with Will.i.am lined up for The Voice UK 2016 final tonight.
That's assuming she's well enough to perform.
Lydia and the remaining finalists will each be singing at least twice tonight, first a new solo song and then with their mentors.
"Mine and Will's performance is going to be absolutely mad," teased Lydia. "It's going to be an epic performance and it's going to be massive. It's going to be brilliant, honestly."
Speaking about working with Will over the past three weeks, Lydia went on to rave about her mentor: "I'd say just getting to know him. He's absolutely amazing and I get to learn something new about him every single time I'm with him.
"He's just a genius and he works in so many areas - he's got so much going on in his crazy lifestyle. I'm glad I can be a small part of it. He's amazing, honestly. I couldn't have asked for a better coach. I'd never change him for the world."
And asked why people should vote for her in tonight's final, Lydia vowed to change the poor track record of The Voice UK's winners.
She told DigitalSpy: "I feel like I've worked so hard to get to this point. I've finally got here, and if they want somebody that's going to work hard and try and make as much success as they can off of it, then I think they should vote for me.
"People say that winners of The Voice don't do that well? I'm definitely going to change that."
However that all assumes Lydia makes the final with the singer having come down with illness over the past 24 hours.
"Lydia has been really unwell and doctors have told her she has to rest," a source said yesterday. "Tomorrow is the biggest night of her life and she is determined to make it to the stage, but right now it is up in the air.
"She has worked so hard to make it to the final, if she can't perform it would be devastating for her."
Lydia will be competing to be named The Voice UK winner tonight against Team Ricky singers Kevin Simm and Jolan as well as Team George's Cody Frost.
The Voice UK 2016 final airs tonight on BBC One from 7PM.
