Sir Tom Jones wants Robbie Williams to play him in a biopic.

The 76-year-old singer has given Robbie, 43, the seal of approval to portray him in a retelling of his life but admitted he would prefer to do the singing himself, despite Robbie's success with Take That and as a solo artist.

He told The Sun on Sunday: ''I said Robbie would be it, maybe it would be better to get an actor. I can always do the voice if needs be so it doesn't have to be a singer.''

Tom also admitted that he has thrown himself into work since the death of his beloved wife Linda last year.

Speaking about seeing a therapist to help him cope, he explained: ''She said 'you've got to carry on, if you don't you'll die'.

''I'm happier when I'm singing than when I'm not. The only time I'd take time off is when I die.''

''When my wife passed away, god bless her, I didn't know whether I would make it.

''I mean I really didn't want to sing. My son Mark helped me tremendously, he said 'you've got to sing' because I didn't know whether I could.''

Speaking previously about the loss of his wife of 59 years, Tom said: ''My wife passed away last year and I am still trying to get over that.

''I don't think if I ever will remarry - the last thing on my mind is marriage.''
