Sam Wilkinson is "really excited" about 'The Voice Kids' final.
The 13-year-old singer will be performing an original song, 'Everything's Alright' and also a duet with his mentor Danny Jones, and is looking forward to being backed by a full band.
Sam said: "I'm really excited to get back on the stage and perform again. It's always fun to play with the live band as well."
Meanwhile, nine-year-old Keira Laver - who has been mentored by Jessie J - is feeling confident about her chances in the final - but also "nervous".
She told the Daily Star newspaper: "I'm confident and a little bit nervous but as long as I know that my family and friends are there to support me, I will be OK.
"I'm gonna turn my negative nerves into positive nerves."
The finalists - which also include Gracie-Jane Fitzgerald, 12, and 11-year-old Lil Shan Shan - admit it will be tough to go head-to-head because they've all become such good friends.
Sam said: "It's been great to meet all the other contestants and we're all really good friends now."
Gracie-Jayne admitted: "It's tough being in a competition when you have made such fabulous friends. You want them all to be there in the final with you."
Danny recently revealed he had asked his McFly bandmate Tom Fletcher to help Sam with his songwriting and to prepare for this weekend's final.
He said: "[Sam's doing his] own song and I brought Tom in to help structure it and give Sam confidence and inner belief to do this for a final.
"I mentor in a way that I want him to have the internal belief to protect him from the external."
The 'All About You' hitmaker is proud his contestant is performing an original song and doesn't think Sam needs much help to become a fully-fledged recording artist, despite only being a teenager.
He said: "He's now an artist. I think this could be released the day after and be successful. He's ready to make an album, he's ready to go."
'The Voice Kids' final airs on Saturday (27.07.19) at 8pm on ITV.
