Born into rock royalty, Jack Osbourne grew up in front of America as one of reality television's first superstars. The son of Black Sabbath frontman and self-proclaimed "Prince of Darkness" Ozzy Osbourne and his wife, TV personality Sharon Osbourne, he came to prominence after starring with his family on MTV's reality series "The Osbournes" (2002-05). Widely touted as the first reality sitcom, "The Osbournes" followed heavy metal's First Family as they worked, played, and argued their way into the hearts of millions of viewers. Osbourne's frequent and intense blowups with his sister Kelly ignited the show's most dramatic episodes, but it was the hilarity and heart of their family dynamic that truly made "The Osbournes" a hit. His young life took a downward spiral following the show's end, from weight issues to a drug addiction that began when he was 13. With his family's support, Osbourne cleaned up his act and emerged a fit, outdoors enthusiast. He documented his passion for martial arts and extreme sports on his own reality series "Jack Osbourne: Adrenaline Junkie" (ITV, 2005- ). Several years after "The Osbournes" mania had settled down, Osbourne reinvented his career by working behind the camera, producing the 2010 documentary "God Bless Ozzy Osbourne." The candid film about his father helped leave behind any public memories of Osbourne's wild child past and established him as a respected auteur.
