As they get ready to go head-to-head with their TV shows Tom Jones has questioned Simon Cowell's ability to judge singing competitions.
The legendary singer who will appear on The Voice UK has said he thinks the Britain's Got Talent judge is unqualified since he has never performed on stage.
"I have problems when people who have never got up on a stage to sing judge those who do. Who are they to say? Simon Cowell is a record man, not a singer," Jones told the Sunday Mirror.
"How can someone give advice if he or she is not qualified? It's like critics who criticise actors, never having been on a stage. Or having a teacher not experienced in teaching.
"The shows with judges from other areas of show business are all very well and good, but The Voice is unique because the four coaches are all singers, can all make records and know what they're talking about.
"I've been approached by other talent shows, not directly, but through my agent and I've always said no because of all that other stuff. I've never wanted to do one until I saw The Voice."
