Ozzy Osbourne thinks tattoos are "addictive".
The 61-year-old rocker - who has a number of etchings on his body - advised his daughter Kelly against getting inked, as many people eventually come to "resent" what they have done.
He explained: "The trouble with tattoos is they're addictive. I've known girls who start out with a flower on their ankle, and three months later they've got an entire battle scene across their a**e.
"When my own daughter got tattoos, I said to her, 'Fashions come and go. One day you may resent what you did to your body'."
The Black Sabbath singer admitted he particularly regrets having a smiley faced etched onto his knee when he was much younger.
Ozzy added to The Sunday Times Magazine: "It's one thing being young and beautiful with a Tattoo, another when you're a grandma with a floppy dagger on your arm.
"There are times when even I wake up and look at the smiley face I drew on my knee and think, 'What the f**k did I do that for?' Getting them done hurts like crazy too."
