Mariah Carey is rumoured to have signed up to appear on X factor next month to promote her new album.

The diva will sing her new single ‘I Stay In Love’ on November 8th.

An X Factor source told The Sun: “Simon loves Mariah — he’s always comparing acts to her. And finally all the compliments have paid off. It’s amazing to have such a big name singing on a British talent show.”

And thrilled ITV bosses are expecting ratings to go through the roof. Our source added: “Mariah is one of the most successful female artists of all time. It’s going to blow Strictly Come Dancing out the water.”
