The ‘Skyscraper’ singer - who entered rehab last November for three months to receive treatment for an eating disorder and self-harming – is thankful for the support she has received from her loved ones and tries to surround herself with people who can help her stay on the right path.

She said: "I surround myself with people that are beneficial in my recovery and my recovery is still a daily battle and I definitely hang out with people that support me in making the right decisions.

"I'm a happier and healthier person today because of the choices I've made.

"Having the support of other artists and musicians and actors is really incredible and I'm thankful for that. I'm thankful to have that kind of support from people I look up to."

Among those who have supported Demi is newly-married Kim Kardashian, who the 18-year-old star describes as a “big sister."

She told E! News: "She's been a friend of mine for a little bit and she's like a big sister to me. So, when she got to announce me performing at the Do Something Awards it was really cool, and we actually got glam together.”
