The first round of X Factor auditions have got under way, but all eyes were on new judges Cheryl Cole and Mel B.

Former Girls Aloud star Cole is returning to the ITV show after four years away.

It is also three years since she was dropped from the judging panel of the American version of the singing competition.

It has been reported that head judge Simon Cowell is hoping for sparks between the singer and former Spice Girl Mel B.
