The youngest child of heavy metal icon Ozzy Osbourne, Jack shot to fame---and infamy---on MTV's reality smash The Osbournes, which chronicled the outrageous adventures of this dysfunctional clan. With his unruly curls, thick-rimmed glasses and dumpy physique, the aspiring music producer fascinated audiences with his profanity-laced rants and frequent trips to rehab. Osbourne initially kept a low profile after the show wrapped in 2004---but when he resurfaced the next year, he was virtually unrecognizable, having lost 70 pounds and kicked his addictions. Over the next four years, Osbourne used his new physical prowess to his advantage and starred in the series Jack Osbourne: Adrenaline Junkie, in which he tried a variety of dangerous and grueling tasks like mountain climbing, extreme marathons and bungee jumping. In 2009, the Osbournes---Jack, Kelly, Ozzy and Sharon---reunited for the variety show Osbournes: Reloaded, but the series was a flop after several FOX affiliates refused to air it due to racy content. Off screen, Osbourne has begun to give executive producing a try and continues to pursue his passion for rock climbing.
