Tom Jones refuses to rap on The Voice

Sir Tom Jones has been angered by 'The Voice' producers wanting him to rap.

The 71-year-old crooner will join fellow mentors Jessie J, will.i.am and Danny O'Donoghue in a special medley of all of their biggest hits at the final on Saturday (02.06.12), but is said to feel annoyed producers want him to rap a section of Black Eyed Peas song 'Where Is The Love?'.

A source said: ''Tom feels silly doing a rap on TV. He thinks Danny or Jessie should do it. So far the producers won't back down and say he has to.

However a spokesperson for the show confirmed nothing had been decided yet.

The representative said: ''The final arrangement for medley has yet to be confirmed.''

The group are set to perform Jessie J's 'Price Tag', 'Where Is The Love?', Tom's 'It's Not Unusual' and The Script's 'The Man Who Can't Be Moved' on the final.

Bo Bruce, Vince Kidd, Tyler James and Leanne Mitchell will all battle out this weekend to win the competition.
