A hypnotherapist from Northamptonshire was hired by X Factor bosses to help singing hopeful, Tamera Foster, cope with the show.
Christian Baker, who lives and work in Daventry, received a call from X Factor producers on Monday last week, asking him to work with the 16-year-old contestant.
Tamera had struggled with remembering her lyrics during and was voted out of the show on Saturday night.
Mr Baker said: “I got the call last Monday and they wanted me to help her. She’d had a tough couple of weeks.”
Mr Baker, who is a qualified and internationally-registered hypnotherapist, travelled to the X Factor house, close to the studio in Wembley, on Tuesday last week to begin working with the singer.
He said: “It was chaotic. A few of the contestants were there and members of production. There was lots going on.”
Mr Baker continued to work with Tamera throughout the week as she prepared for her live performance last Saturday night.
Some of the sessions were was filmed for the ITV show, which was watched by millions of people each week, while others were in private.
Mr Baker said: “There’s been a lot in the press about Simon Cowell hiring a hypnotherapist to help her learn her lines. But it wasn’t specifically that. She’s only young and it’s a massive show. I helped her to deal with the stress, pressure and anxiety and to focus on the words and stop thinking about the negatives.”
