Ozzy Osbourne and his wife Sharon are celebrating the latest addition to their family. On Tuesday April 24, their son Jack and his fiancée Lisa Stelly welcomed a new bouncing ball of joy into the world and named her Pearl. The healthy baby weighed in at 8 lbs. and 6 oz.

This is not the first grandbaby for the Prince of Darkness, who already has four grandchildren from his past marriage, however this is Sharon’s first biological grandchild. She beamed with pride and happiness on her daytime show ‘The Talk,’ saying, “Today I witnessed my first grandchild being born, (a) life changing experience. She is an angel."

Sister Kelly chimed in on Twitter as well, saying, “I am one proud Auntie!"

While the family seems to be picture perfect these days, that was not always the case. Television viewers watched Jack and his sister Kelly grow up before their very eyes on the hit MTV reality show ‘The Osbournes.’ Thriving on their quirky disfunctionality and apparent addictions, the show displayed a personal and somewhat dark side of the Osbournes, which fans had never seen before.

However, since the show wrapped and years have passed Kelly and Jack have gone through rehab, both seemingly turning their lives around and both pursuing professional careers in show biz. The bigger surprise is that their dad Ozzy has been sober for over five years, proving that it's never too late to be a great dad.

In 2011 Jack even produced a documentary about his father called ‘God Bless Ozzy Osbourne.’ The film, an epic tale of Ozzy's life takes fans through both the good and the bad in this honest look at a father from a son’s point of view – quite fitting given that Jack is now a father himself for the first time.

Congrats to the whole Osbourne family on their new Pearl!
