JACK Osbourne says his 22-month-old daughter Pearl used to be terrified of her grandfather, rocker Ozzy Osbourne, because of his long hair.
The Black Sabbath rocker dotes on 22-month-old Pearl - the daughter of his son Jack and his wife Lisa Stelly - and though they have "fun" together, the youngster used to be nervous around him because of his long locks.
Jack said: "She was scared of him for a while because she had this weird thing about if you had long hair, so now that she's grown past that insecurity, she likes him.
"My dad is really enjoying being a grandpa, but I think what he enjoys most is that he can have fun and then when it's no longer fun, he can just hand her off."
Jack, 28, says his daughter is a "girly girl" who loves dressing up in her mother's clothes - particularly her underwear.
He told PEOPLE: "She likes putting on her mom's jewellery, walking around with handbags and she loves putting bras on.
"It's really funny. She'll go and grab one of her mom's bras and gets angry if you don't put it on her."
The former 'Adrenalin Junkie' host - who was diagnosed with multiple sclerosis (MS) just weeks after Pearl's birth in 2012 - adores the fact his daughter loves to give him hugs.
He said: "She's actually really hugging back -- a real deep hug -- and I like that. [She] wraps her arms around my neck and just gives me a good squeeze."
