McElderry reveals fears ahead of opera TV show
Joe McElderry thinks he is "stupid" to appear in 'Popstar to Operastar'.
The 19-year-old star - who won 'The X Factor' in 2009, only to be dropped by Simon Cowell's record label 18 months later - explained he is hoping to master the art of opera singing on the ITV1 show, to the extent that he sounds like Pavorotti.
