NOW WATCH: All the winners of The X Factor so far
This year Dalton Harris won the show with his James Arthur duet The Power of Love. Speaking to heat about his reaction to his name being announced, he said: "I blacked out; I’m being honest. I blacked out. Anthony was third and he did his roll thing. I was like ‘cool.’ Then I heard ‘and the winner is…Dalton.’ Then my ears stopped working and [my face] was on fire and I don’t remember anything.
"I remember faces and [I woke up in] Louis’ dressing room. James Arthur gave me this [brooch], then I had to leave to go to the hotel. I went and said ‘thank you,’ then I met my adopted dad and friends that had come. Then I went to bed."
