Kelly Osbourne has therapy once a week to help with her addictions.

The 33-year-old star - who has been open about her alcohol and drug addictions in the past - thinks everyone should go to therapy to keep their ''mind good'' but acknowledged the huge stigma surrounding it.

She said: ''I believe everybody should have therapy. There's still a huge stigma, especially in this country. You work out to keep your body good so you go to therapy to keep your mind good. Your mind, body and soul are the full package. I try and go once a week.''

However, Kelly doesn't believe therapy or medication works unless you really want to make it work.

She added to The Sun's Bizarre column: ''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 had previously revealed she was locked in a mental institution for three days for her drug and alcohol addiction.

She shared in her recent memoir: ''Mum once locked me in a mental institution for three days and it scared the hell out of me ... I had to wear paper shoes, since I could potentially kill myself with a shoelace and wasn't allowed to have anything metal not even a spoon. I was suicidal by medical standards but I heard mum's message loud and clear: stop using drugs before I was gone for good.''

In 2009, Kelly revealed she found drugs when she was 13-years-old after getting liquid Vicodin when her tonsils were removed but her substance use got heavier when her mother had cancer and her father almost died in 2003.

She shared: ''The only way I could even face my life was by opening that pill bottle, shaking out a few pills - or a handful - into my palm and throwing them down my throat.''
