Should X Factor supremo Simon Cowell be scared? Well he might be after Gary Barlow declared that he is going to get revenge on the media mogul in his own tell all book.
Now Gary seems like a gentle soul to us so we're not sure if he was just having a laugh...
According to the Metro, the judge, who was reportedly branded "boring and stale" in journalist Tom Bower's book: Sweet Revenge: The Intimate Life Of Simon Cowell, said: "Wait until my book comes out - it will be b****y beautiful. I'll get the lot of them."

The judge also commented on the communication the judges have with Simon who is currently sitting on the X Factor USA panel alongside Britney Spears, Demi Lovato and L.A. Reid, saying:
"We get messages every couple of weeks. He gets the show sent to him," he said. "He approves it but I think they are probably quite busy over there at the moment."
Commenting on the claims made by Bower that Simon mocked his OBE for organising the Queen's Diamond Jubilee concert, Gary added:
"I've had plenty of abuse in the last 22 years. I'm used to it. I'm so used to having people saying things about me and then when I meet them they've never said things. I rake it all with a pinch of salt."
Speaking what he wants to get out of this year's X Factor, Gary who has returned to the show for a second year, said:
"I want to have just more fun this year and I already have. I had tremendous fun in the auditions, really enjoyed it. I feel a lot more comfortable doing this this year. I'm looking forward to it."
The first live show kicks off this Saturday. We can't wait! Will you be watching?
