Former Spice Girl Mel B was left red-faced after she was introduced as Mel C during X Factor auditions.

The 37-year-old singer, who appeared as a guest judge, was embarrassed after the blunder at the Manchester auditions.

According to the Daily Star, the mistake was made by a member of the production team who introduced her to waiting fans by saying: "Please welcome Mel C!" before quickly correcting himself.

A source at the auditions told the Star: "It was a bit awkward, everyone looked around for Mel C. The poor guy realised he'd made a mistake but Mel didn't look to pleased."

Mel B became the latest star to step in to the vacant judge seat alongside permanent judges Gary Barlow, Tulisa Contostavlos and Louis Walsh.

Rita Ora, Leona Lewis and Geri Halliwell have also been made guest appearances on the panel during the auditions stage.
