Ozzy Osbourne became the world’s most watched rock dad when he invited TV viewers into his home on his MTV reality show ‘The Osbournes.’

Known as the ‘Prince of Darkness’ throughout his music career, the show offered fans an intimate look at a completely different side of Ozzy, and his loving yet off-the-wall relationship Kelly and Jack, two of his five biological children (Ozzy and Sharon also helped raise a child named Robert).

It’s hard to believe that the show wrapped up way back in 2005 but with Jack welcoming his first child into the world recently, Osbourne now has six grandchildren, as well.
