A couple of photos of BLACK SABBATH legend Ozzy Osbourne spending quality time with his new granddaughter, Pearl, can be seen below (courtesy of Jack Osbourne's Facebook page and Twitter account).

Ozzy's wife/manager Sharon Osbourne became a first-time grandmother on April 24, 2012 when their 27-year-old son Jack and his now-wife, actress Lisa Stelly, welcomed Pearl at a healthy 8 lbs., 6 oz.

Ozzy already had four grandchildren; two each from daughter Jessica and son Louis from his previous marriage to Thelma Riley.

Introducing his daughter in Hello! magazine, Jack said, "People say when you have a kid, it's like instant love, but unless you've experienced it, it's impossible to comprehend.

"The moment I saw her, I felt more love than I'd ever felt for anything. It was the weirdest, most overwhelming thing."

It is the first child for Osbourne and Lisa Stelly. At the time, Sharon said, "I'm happy because it's what Jack wants, so I'm happy. And I've always wanted to be a grandma, so it couldn't be better."

Jack found fame through his family's MTV reality show "The Osbournes" and has since appeared in several other TV programs. In 2011 he produced a documentary about his father called "God Bless Ozzy Osbourne" which, according to The Telegraph, contained admissions from the singer's five children that Ozzy was not a good father in their younger years, and that their abiding memories were of him hopelessly intoxicated, or, more usually, absent altogether.
