Kelly Osbourne has revealed her mum put her in a padded cell to get her on the straight and narrow.
She said that X Factor judge Sharon Osbourne took the unusual step to try to cure her of her drug habit.
Kelly told Cosmopolitan magazine: “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 learnt 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.”
Kelly, who is engaged to Matthew Mosshart, said she finally got herself together after realising that she wasn’t pleasant to be around.
“What changed for me was looking around and seeing that nobody liked me or wanted to work with me,” she said.
