London - Jessie J is in trouble with X Factor bosses for revealing she is going to be a guest mentor on the show.
The Price Tag singer recently revealed she will be joining judge Tulisa Contostavlos in Greece later this month for the Judges' Houses stage of the competition, but found herself in hot water with producers because it was supposed to be a secret.
She told the Daily Mirror: "I accidentally leaked it. I wasn't supposed to tweet about it. It was a secret and I got told off."
Twitter blunder
Jessie - who will help the N-Dubz star pick the best three groups to progress to the live shows - revealed the news after replying to a question from one of her twitter followers.
One wrote: "WOW @jessiejofficial appearing on UK XFactor as guest mentor with Tulisa?!? (sic)"
To which the pop star replied: ";) yeeaahh man! (sic)"
Louis Walsh is reportedly set to be joined by 80s pop icon Sinitta at his house when they pick the over-25s, and Kelly Rowland is thought to be linking up with Jennifer Hudson as she takes charge of the girls.
Gary Barlow will look after the boys in Los Angeles and will be joined by his Take That bandmate Robbie Williams - who has appeared on The X Factor several times.
