Jack Osbourne -- the son of heavy metal rocker Ozzy Osbourne and his music manager-turned-talk show hostess wife, Sharon -- emerged as a star on his family's MTV reality series, The Osbournes (2002-2006). That program took a darkly comic look at familial dysfunction among the wealthy and privileged -- and netted the highest ratings of any single series in MTV history. By the time it wrapped, Jack in particular began to clean himself up; he dropped his alleged excessive drinking, lost over 50 pounds, and emerged triumphant. MTV rejected his pitch for a reality series of his own (reportedly arguing that he couldn't carry it); he instead starred in Jack Osbourne: Adrenaline Junkie -- a U.K.reality program that found Jack and cast mates traveling the globe to participate in "exotic" sports such as running with the bulls in Pamplona and engaging in Thai boxing. In early 2007, Osbourne also participated in the short-lived reality series Armed & Famous, in which he and other celebrities (including Erik Estrada and LaToya Jackson) spent time as officers with the Muncie, IN, police department.
Osbourne continued to appear in a number of reality shows, including a stint I'm a Celebrity, Get Me Outt of Here in 2010 and on Dancing with the Stars in 2013. He also branched into producing, and made a documentary on his father.
