James Arthur was crowned the winner of X Factor 2012, beating Jahmene Douglas to the title.
The singer-songwriter, from Middlesbrough, took the title in front of a screaming 10,000-strong audience at the Manchester Arena.
Singer-songwriter James looked stunned as host Dermot O'Leary announced the result and could only say "wow" when asked how he felt.
"I don't what to say," he added.
Afterwards on the Xtra Factor he declared his love for mentor Nicole Scherzinger, who he previously said was so beautiful he couldn't talk to her.
He said: "It's not quite sinking in. I love you with all my heart. You've been the best mentor and an amazing friend."
Former Pussycat Doll Nicole, who was the judge responsible for both the acts in the final, said: "I watched him up there and he wasn't even supposed to win this because he doesn't fit in the box.
"He is a fighter and he willed this to happen. He deserves this so much especially from where he's come from. This is my first year on the UK X Factor and it's been an honour."
Rival judge Gary Barlow praised the X Factor winner, saying: "He kept being true to himself. Being the artist he always wanted to be. He's won despite been in the bottom which is amazing."

James walks away from the talent show with a recording contract and will now release his winner's single, a rendition of 'Impossible' by Shontelle, in a bid to top the charts with a Christmas number one.
The track is available to download already and will be rush released in the shops from this Wednesday December 12 - with all proceeds going to charity Together For Short Lives.
James said: "I am absolutely overwhelmed to have won The X Factor. I am lost for words. To have been be able to perform my winners single was just insane. I love the song and am so glad that proceeds of the single will be going to such a great cause."
Runner up Jahmene said he was blessed to have been part of the show. He said: "I've learnt to let go and let things be."
Asked if he'd have done anything differently he joked: "Err go on Strictly Come Dancing."
Superstars One Direction, Rihanna and Emeli Sande also took to the stage in the two-hour final, which was one of the CLOSEST EVER.
Finalist Christopher Maloney, who left the show last night, caused controversy behind the scenes when he walked away from the final earlier in the day - allegedly saying he wanted nothing more to do with it.
There was speculation that he was actually ASKED to leave after he had a boozy night following being voted off and then apparently got mouthy in rehearsals when he realised he only had one line in the group song.
After James was declared winner, celebs rushed to congratulate him including Cheryl Cole and Little Mix.
Cheryl, who used to be a judge on the show, tweeted:"Congratulations James Arthur. True Talent!!"
