As well as featuring on The X Factor USA this year, Mariah Carey could also appear on the UK series as a guest judge, according to reports.

Carey is set to take up a role on the US show, in the form of assisting Simon Cowell at the judges’ houses, but The Mirror reports that the singer will become a guest judge for one week only during the live shows.

Simon and Mariah are said to have had talks in France about a possible role on the ITV show, and a source said: “Simon has created a unique role just for Mariah after plans for her to be in the original US judging line-up fell through.

“The idea is for Mariah to assist Simon at the judges’ houses stage of the US show, as well as helping the other judges. It is yet to be confirmed, but the other plan is for her to be given a special, one-off fifth judge role on the British show.”

What do you make of the idea of having a fifth judge on the panel?
