Demi Lovato: We need idols

Demi Lovato thinks young people need "someone in the spotlight to idolise".

The 21-year-old singer went to rehab in 2010 to work through "physical and emotional issues" and since receiving treatment she has been vocal about causes dear to her heart.

Demi believes it is essential she use her fame to make a difference in the way society operates.

"When I was younger, I needed someone in the spotlight to idolise, who stood for positivity and light and happiness, and wanted to change the world," Lovato revealed in the summer issue of Cosmopolitan for Latinas.

"And because I didn't have that, I realised I want to do that, if only for my 12-year-old little sister."

Demi is happy she put an end to her partying ways, as sobriety has made her more appreciative.

"I was used? to drinking and doing drugs on my birthday. I always imagined my 21st being a huge party where I'd get sh*t-faced and go crazy. But I realised that there's so much more to life than that," she explained.

"Imagine walking 10 miles a day just to get water for your family? We have so much to be grateful for."
Demi is focused on making good music that will last the ages.

The songstress wants to continue growing as an artist and she has huge professional plans for the future.

"I'm very proud of how far I've come, but I definitely want to win a Grammy one day, and I dream of winning an Oscar," she said. "I want to continue to tour and build my fan base and make music that will last for decades."
