Kelly Osbourne graces the cover of the September 2013 issue of Cosmopolitan UK. In a revealing interview with the magazine, the 28-year-old Fashion Police correspondent opened up about her past struggles with drug use.

On her past drug addiction: “I’ve been to rehab seven times and to two mental institutions. My mum even had me put in a padded cell once to scare me, but like a brat I just sat it out until she said, ‘Well, that’s not going to work’. But what I’ve learned is that no amount of therapy or medication is going to work unless you want it to. Until you want to be a good person, you will never be one.”

On why she got help: “What changed for me was looking around and seeing that nobody liked me or wanted to work with me.”

On staying true to herself: “I can’t lie; it’s been hard having people say, ‘You’re fat’, and, ‘You’re a beached whale’. But I’ve been judged since I popped out, and I’ve never known anything else. What’s been great is overcoming that and understanding that these people are just idiots who hurt your feelings because they want a reaction. I’m proud of proving them wrong.”
