Louis Walsh has been having singing lessons ahead of a performance with Union J.
The 'X Factor' judge had been working on his vocals to take to the stage with the boy band for the final of the competition in Manchester on Sunday (09.12.12), and despite being voted off the ITV1 show last night (02.12.12), meaning the performance will not take place, the group still want to sing with Louis at some point.
Speaking exclusively to BANG Showbiz, the foursome said: "We will still perform with Louis Walsh, don't you worry about that. We got him singing lessons and everything the other week.
"He doesn't do the 'X Factor' tour I don't think, but we will find someway of getting him on that stage ... in a onesie. He loves onesies deep down."
Louise donned a onesie - a comfy all-in-one garment - on Saturday night's (01.12.12) 'X Factor' show after promising Union J he would do if they reached the semi-final of the competition, and the boy band insist they will be "eternally grateful" to the music mogul for being the "driving force" behind their success.
The group - made up of Jaymi Hensley, JJ Hamblett, George Shelley and Josh Cuthbert - added: "Without him Union J wouldn't be where they are today. There is no question about it.
"He's the driving force behind this and he's completely pushed us to make us better because he believes in us and we will be eternally grateful to him.
"He is so proud. He's been a big part of our lives for the last two months or so. We hope he'll keep in contact and give us the advice that we need because he's so experienced. He's been there for us whenever we've needed him. We're like a team and we're so happy we've come fourth."
