Why Does Demi Lovato Think Everyone's A Serial Killer?

Demi Lovato has overcome many struggles throughout the last couple of years and seems to be on the right track with her life at the moment. The 19-year-old former Disney star has a successful album out, a tour and is a new judge on reality competition series The X Factor. Demi, who has been praised for her work with speaking out on self-esteem, is on the cover of the new issue of SELF magazine and further opens up about her problems, but also tells the mag she's changed her life around - but with her new lifestyle, she suspects that everyone could be a murderer!

Demi tells SELF: 

"I surround myself with people who make positive decisions and who have more interests than wanting to go to clubs and get wasted. My friends and I look out for each other, and I love just inviting everyone over to watch TV. I like 'Law & Order'—except it makes me want to go out and inspect everyone on the street to see if they're a serial killer!"
