34-year-old Christopher Maloney wowed the judges in Liverpool on The X Factor 2012 tonight.
The Customer services advisor brought along his nan, Patricia, his biggest fan to help cheer him on.
"This X Factor is the biggest thing that I’ve ever done. I didn’t realise how big the crowd was gonna be. I’ve never applied for anything like this before, it’s took me five years to actually build up the courage to apply," Christopher revealed. "I’ve downloaded the application form, filled it out, put it in an envelope and ripped it up every year.
"I’ve always wanted to sing but people have discouraged me and said that you know, you’re not good enough. They have really knocked my confidence, they’ve discouraged me from applying, in my head I just think I’m not good enough and that’s what has stopped me from doing it.
"Me and my nan are dead dead close, me granddad died and then I moved in with her to look after her. Me nan's the only person that’s believed in my singing."
He added: "This means everything to me, I’ve never sang in front of thousands and thousands of people before and it’s just going to be a shock to the system."
On stage, and Christopher's nerves couldn't be hidden from the judges.
"Are you shaking?" asked Tulisa. "Do you want to calm down and breathe."
Singing The Rose by Bette Midler, Christopher revealed: "It will mean the world to me, the song that I’m singing was played at my grandad’s funeral and that meant a lot to me, it was a celebration of his life and this means a lot to me and that’s why I feel like I want to sing it today for you."
A stunned Gary reacted: "34. How the hell have you kept that voice hidden till now?"
Christopher revealed: "I’ve never put myself out like this before and I’ve just bit the bullet today and just gone for it."
Tulisa asked: "Do you not believe in yourself? Can you not hear yourself when you sing?"
Christopher replied: "People have said that you know, don’t come on here because you’re going to embarrass yourself, you’re going to make a show of yourself."
Guest judge Geri Halliwell added: "I think you’re going to be a star."
"You stole the show today, nobody else is going to get that reaction," Louis said.
Tulisa commented: "Christopher I am so happy that you got to sing that song for your granddad and I’m telling you that he is up there and he can see you and he is the proudest man in the world."
After Christopher left the stage, Gary told the other judges: "He was so nervous and I just thought this can only go one way and I just couldn’t believe it when that voice came from nowhere!"
Meanwhile offstage, Christopher reacted: "I‘m absolutely amazed, I didn’t expect that reaction at all, I just didn’t expect anything like that at all."
