Cheryl Cole says Simon Cowell is "doing my head in"

London, Sep 13 : Popstar Cheryl Cole has reportedly blasted fellow X Factor judge Simon Cowell, saying: "You are doing my head in."

According to reports, the stunner is upset with Cowell for poking his nose in her decisions.

The 'Girls Aloud' popstar has accused Cowell for not letting her make her own decision while judging the contestants on the show.

The tiff took place when Cowell termed one of Cole's favourite contestant's as 'sub-standard'.

During the show, Cheryl admits she is fighting a losing battle - then Simon smirks: "You don't want to do this anymore, do you?"

The beauty then snaps: "I do, but it's you, Simon - you are doing my head in."

The row continues when Simon tries to convince her a girl she has doubts about is ready for the show.

Cheryl rages: "I don't have to give her a shot because you are telling me I have to."

She adds: "I am going to make my own decision."

The singer and Louis, 56, start sniping during a girl band's audition when the Irish judge makes a joke about similar acts who can't sing, and adds: "You know about girl groups, Cheryl."

She hits back: "That's right Louis, and you don't."
