The Pussycat Dolls star has been filling in on the boot camp section of the show while Cole recovers from Malaria.

But according to the People newspaper there is bad blood between the two divas. It’s claimed Chezza has text Simon Cowell to express her dismay at the move apparently writing “I can't believe you got her.”

X Factor boss Cowell recently revealed that the Girls Aloud star is getting better and sending him messages.

He said: “The worst is over. The texts are getting increasingly feisty so she's obviously on the mend… but our job is to make sure she doesn't come back too quickly.”

And the new X Factor contestants themselves to have been getting feisty too.

Police were called to a Wembley hotel where they were staying on Friday after they got rowdy and property was damaged.

A spokesman for the show said: "Contestants had an opportunity to relax after a week of intense rehearsal and performance.

"We have spoken to the individuals concerned, who have apologised for their behaviour."
