I don't think she was the best judge but she should have stayed. Unless they get some brilliant judges, it's going to flop without Cheryl, Simon and Danni.
During discussions for me to return [to The X Factor] it became clear that unfortunately, this year, The X Factor audition dates in the UK clash with the live shows of Australia's Got Talent during June and July. For this reason I am unable to return
Dannii was the best one! They should try to get Kylie to replace her.
