Britain's Got Talent 2018 finalist Calum Courtney has let slip his song choice for tonight's show.
The 10-year-old school pupil from Essex was one of the first acts to audition for the new series last month.
He's now through to the live final after finishing in the top two in the second semi-final.
Back in his audition, Callum performed Michael Jackson’s “Who’s Lovin’ You”.
And he'll be reprising that track for tonight's live show.
Calum teased: "It's going to be a more upbeat one, with a little bit twist to it."
He added: "Thank you to everyone who vote for me, it's such an inspiration for my little brother."
Back during the auditions, Calum told cameras about his love of singing: "I love singing. I've got a really musical family. My nan was in the West End and I thought, if she can do it, I can do it. She's amazing and I love her.
"If I got four yeses from the judges, I would probably cry and faint."
"What a big song for such a little guy," David Walliams told the youngster after the performance.
"That was one of the biggest reactions we've had from anybody, it was fantastic," Amanda Holden added after the crowd were left up on their feet.
And Simon Cowell told him: "You totally controlled the song. This was special and I like you a lot."
Joining Calum in tonight's final show are acrobats Giang Brothers and comedy singer Micky P Kerr, dancers DVJ, father and son singing duo Tim and Jack, comedian Robert White, singer Gruffydd Wyn Roberts, singer Donchez Dacres, comedian Lost Voice Guy and the D-Day Darlings in the final.
Joining them will be an eleventh wild card act, as chosen by the judges.
Up for grabs for the winner is £250,000 cash prize, a spot on the Royal Variety Performance and a special prize from Simon Cowell.
The final will also see performances from The Cast Of Magic Mike from Las Vegas and the Cast Of Tina Turner The Musical
The Britain's Got Talent 2018 final airs Sunday, June 3 at 7:30PM.
