Demi Lovato claims Kim Kardashian's curves have ''revolutionised'' perceptions of beauty.

The 'Skyscraper' hitmaker is a huge fan of the 'Keeping Up With The Kardashians' star's voluptuous figure and believes she has encouraged more women to embrace their bodies by proudly displaying her curves.

Demi said: ''The trend has started to become less about super, super skinny models. That was completely unattainable for anybody.

''Kim Kardashian, say whatever you want about her, but she's revolutionised what's expected with curves nowadays.''

The 22-year-old singer - who has suffered from an eating disorder in the past - loves to show off her own ''assets'' and is particularly proud of her posterior.

She said: ''What makes me feel sexy is being able to rock no makeup wherever I go. Also wearing pants or skirts that showcase my beautiful assets. It's my butt. I love my butt. Hopefully it stays that way.

''I really love to accept my body for what I am.''

Demi also confessed to sticking to a strict beauty regime to keep her skin looking good.

She said during a video interview with Allure: ''I do have a regiment and I stick to it. No matter how tired I am I always take my makeup off before I go to sleep. I always wash my face, use good toner, sometimes a serum. Then I wear a really thick night cream.''
