Rocker Lemmy has vowed never to reveal his identity to the secret child he gave away.

The Motorhead frontman has two sons, 38-year-old music producer PAUL and another who was put up for adoption as a baby.

And Lemmy insists the man is better off without knowing the true identity of his father.

Lemmy says, "He's a computer programmer. His mother went and found him. She's a social worker and wears these diaphanous paisley smocks.

"She said he put his head in his hands when she told him she was his mother so she hadn't the heart to tell him who his father was.

"I figure if I go and meet him for the sake of my curiosity, it might ruin his life. It's better for everyone if I don't.

"I never met him so I don't miss him."
