Successfully Rehabbed: Jack Osbourne
Kelly isn't the only Osbourne sibling to sober up! Jack made a drastic lifestyle change when he checked into adolescent psych ward in 2003 for an addiction to OxyContin. After rehab, Osbourne appeared on 'Celebrity Extreme Detox' and 'Jack Osbourne: Adrenaline Junkie'. In the shows, Jack displayed his eagerness to take up a healthier and more active lifestyle.
