Sir Tom Jones has revealed he dreams about his late wife and is devastated when he wakes up to realise she is not there.
Lady Melinda Rose Woodward died from lung cancer earlier this year at the age of 75 after the couple were married for 59 years.
He told the Sunday People: "I hear her voice. I see her a lot at night.
"When I dream that she's still here and then I wake up and she's not, that's the hardest."
The singer admitted he cannot contemplate finding a new relationship, saying: "I haven't even thought about that - I really haven't.
"It was a devastating thing because we found out she had lung cancer - she didn't know. She had emphysema, you see, then all of a sudden, boom. I was on tour at the time and I came home and they didn't know how long we had.
"It was terminal. So I had to stop at that point and I didn't know whether I would be able to sing again because it hurt so much because we had been together since we were kids.
"It's still hard. I didn't know whether I'd be able to get up on stage and be emotional with songs, especially songs that she liked. But I can be and it's lifted me up and she's there."
Sir Tom will soon be back on TV when The Voice UK switches to ITV and airs next year.
The veteran coach will be joined by will.i.am and newcomers Jennifer Hudson and Gavin Rossdale in the famous red revolving chairs.
He previously slammed the BBC for dropping him in 2015 and said he has not received an apology.
