X Factor judge Cheryl Cole has admitted that Simon Cowell knows just how to wind her up. She revealed that things get very tense between all the judges on Saturday nights and accused Simon Cowell of being particularly competitive.

Cheryl told BBC News: “There is tension between us on the actual Saturday night, when he starts getting annoying and saying nasty things.

“It gets quite heated backstage, and quite competitive. I don’t feel like I’m a competitive person.

“I feel like the best person should win The X Factor, whether they’re in my category or not.

“But he’s so competitive and so rude sometimes that I find myself getting caught up in it.”

“Honestly, he’s really annoying. Really annoying.”
