Despite the glitch, Cheryl continued to sing and dance to the lead single from her recent solo album A Million Lights, with only parts of her vocals audible.

In a message on Twitter after her performance, Cheryl said: "I really dn't feel upset abt the tec issues during my performance and chat.

"I just hope every1 commenting on it has done their part 4 the cause."

Cheryl's TV performance came on the same day that she joined her Girls Aloud band mates at a press conference in London to announce their comeback tour and album.
