Sir Tom Jones has admitted that he regrets spending so many years covering up his grey hair.
The Voice star, 71, surprised fans three years ago when he finally stopped colouring his trademark thick, curly locks.
He told the Radio Times magazine: "To each his own. It's not for me to tell others what to do. But you can't get to a certain age and have black hair. If some can, bless 'em."
The Sex Bomb singer revealed: "Every Christmas I'd take two months off and never dye my hair. And when I started a new tour, I'd look and think, 'It's not white enough, a bit patchy', so I'd dye it again.
"It must have looked pretty obvious. I should have let it go five years earlier."
Sir Tom told the magazine: "Getting older is great. I look forward to birthdays. It's very sad if you moan that 'it's not like the old days'.
"I know entertainers who do that, and claim the music isn't so good. Bulls***."
The Welsh star, a coach on hit BBC1 talent show The Voice, said he was sad to have given up his annual stint singing in Las Vegas last year but that he had been "flogging a dead horse" and was "taken for granted" because he had been there for so long.
"My voice is as strong as ever. Hopefully, when it's not, I'll stop. It can't be far away, but I hope it's a long way off," he said.
