Cheryl Cole hit X Factor co-star Simon Cowell after he poked fun at her dress on Saturday night, a report has claimed.

The Girls Aloud star was allegedly left furious after Cowell warned her live on air that she was in danger of falling out of her frock.

According to The Sun, Cole went on to "belt" the music mogul when the show went to an advert break. She is said to have shouted: "Why did you do that? What did you do that for?"

A source said: "Cheryl tried to compose herself, but she was furious at Simon. She felt there was no need to mention it on air - he could have waited and said something discreetly.

"But the dress was risqué. From the side you could see everything. Some of the risqué outfits just don't work outside of a fashion shoot."

It is not the first time that Cole has been accused of hitting the programme's boss. Last year, Cowell's sidekick Sinitta said: "When [Cheryl] performed with Girls Aloud and Simon had a dig at her, she slapped him afterwards."
