X Factor wannabe Shaz Paz says she was 'used' by the show's producers.
The carer was seen at the weekend forgetting the words to Kiesza's Hideaway having originally wanted to sing Michael Jackon's Man In The Mirror.
Watching the show back at the weekend, Shaz explained: "My first reaction was, 'Oh my gosh, they've used me to make me look bad'.
"I was gutted. I feel deflated but on the upside I trended on Twitter.
"I knew I was going to forget my words and that was bugging me.
"I stood singing and when I got to the second verse I forgot them and I knew it was do or die."
However Shaz - who also alleged that Simon Cowell somehow "forced her" into saying she was classically trained - did love her moment in the spot.
Having performed to a audience of thousands at Wembley Arena, she confessed: "It was my dream to dance in front of a crowd like that. It was on my bucket list."
The 43-year-old from Kent appreciated the support she got from the the audience and some of the judges, telling the Daily Mirror newspaper: "Cheryl was fascinated with my slide and found it entertaining and Grimmy loved the thumbs up move and again said it was entertaining.
"I didn't know the crowd were watching (when I was dancing), I just got carried away and kept on doing it.
She added: "It (dancing) just makes you feel good, especially if people are watching and when the crowd gets involved."
The X Factor continues this Saturday and Sunday night on ITV.
