The X Factor's Brian Friedman has revealed he thinks the pressure is starting to get to contestant Fleur East.
The 27-year-old singer has been getting more and more positive comments from the judges and is now being tipped as a dead cert to make the final, along with favourite Andrea Faustini.
Brian, the show's creative director, said: "I think Andrea has felt that pressure from the beginning, and is sort of used to it now. He just goes out there and does a great vocal, he's not really concerned about the stress of it.
"Fleur - I think she definitely has more pressure put on her back, because every week she's getting better and better.
"She wasn't a shoe-in from the beginning, the judges were saying, 'You're maybe not doing the best that you can.' But now that she's getting all those positive critiques she's set the bar really high for herself."
The X Factor choreographer, who attended the Global Gift Gala along with Victoria Beckham, Eva Longoria, Simon Cowell and Ricky Martin, also revealed viewers can expect to be wowed by this week's Whitney Houston versus Elton John theme.
Brian said: "Whitney and Elton are all about the glitz and the glam. Big vocals. And Stevi's still in there so I'm sure we're going to have some wow moments."
