Donny Osmond - Osmond To Become A Grandfather At 47

Seventies pop star DONNY OSMOND is celebrating after learning he's to become a grandfather at the tender age of 47.

Youthful-looking Osmond - who recently shattered his wholesome image by revealing he once trashed a hotel room - was pleased when his second son JEREMY, 24, announced his wife is expecting a baby in August (05).

Osmond says, "I'm going to be one of the youngest grandpas around. I can hardly wait."
