- Kelly Osbourne
Coming in at number 9 on our list is British singer-songwriter, fashion designer, activist and TV personality Kelly Osbourne. Known for her work in Shut Up, Sleeping in the Nothing, The Osbournes, Fashion Police, Dancing with the Stars and Australia’s Got Talent, this two-time Teen Choice award-winning star was addicted to painkillers. After coming out to her family about the same in 2004, she entered a drug treatment centre the very next year after a relapse. Four years later in 2009, she entered another drug treatment facility and stayed there for a month after experiencing a relapse due to her addictions. After that, she went on to say that was the first time she really felt that rehab helped her.
