X Factor contestant Kye Sones reportedly used to front a band once signed by Sony Music.

The chimney sweep impressed the judges and audience with a mash-up of Rita Ora's RIP and Save the World by Swedish House Mafia during the auditions.

According to The Sun newspaper, it has been revealed that Sones was previously part of electronic act Diagram of the Heart, who had toured with Scissor Sisters.

It is further reported that the group had recorded a song called Dead Famous, which criticised reality singing shows like The X Factor.

However, the band went their separate ways in 2011 before releasing a studio album.

An X-Factor representative said: "People with raw talent all stand the same chance in the competition, whether they have been in the business before or not.

"The level of talent is extremely high again this year - with people from all walks of life entering the competition. Kye will still need to be mentored and developed if he gets through to the live stages."
