Spice Girl and Superstar judge Mel C has released showtune "I Don't Know How To Love Him" from Jesus Christ Superstar as her latest single.

Mel will also perform the song in character as Mary Magdalene in the upcoming stadium tour of JCS, in which she will star alongside Chris Moyles as Herod, Tim Minchin as Judas, and whoever wins the chance to play Jesus in the Superstar final this Wednesday.

The single might whip up some extra support for the otherwise flagging TV casting show, which has suffered poor ratings and been lacerated by critics. Do tell us what you think.
