Girls Aloud star Cheryl Cole has told Simon Cowell she will leave The X Factor if fellow judge Dannii Minogue is replaced on the show’s judging panel. Dannii has long been rumoured to be being replaced as Cowell wants to continue revamping the show’s format. "Cheryl told Simon straight - if it's not her and Dannii together, then he's looking for two new stars,” an insider told The Sun. "There's no way he will let them both go. The show was a bigger success than ever and Simon knows a lot of that is down to Cheryl."
