The Six Chair Challenge started on the 27th July, where it was shown that Sharon Osbourne was mentoring the Girls category. It was also revealed that Simon Cowell would be mentoring the Groups, Nicole Scherzinger would be mentoring the Overs and Louis Walsh would be mentoring the Boys.
In a change to previous years, each judge faced their category alone while the other judges sat on the sidelines offering their critique.
