'Neon Lights' beauty Demi Lovato has confessed that her friends are all motivated and inspirational people, and she thinks it's important to be surrounded by people like that because it keeps her head in a good place.

Speaking exclusively to Seventeen magazine, the songstress explained that she is careful to keep people around her who share the same sense of ambition and drive, and general excitement about their lives:

"I like to have friends in my life who believe they're going places and are working toward their dreams. When you're growing and the people around you aren't, that's when you have to start shedding them. I've done that a lot over the past few years, but it has been so worth it, because the people in my life today inspire me to keep being creative, to have fun, and to be a good person."

She went onto add that fame is great, but she feels more fulfilled when she does things that mean she can 'give back':

"When I give back, I don't question my self-worth. I know that if my career were to fall apart tomorrow - even if I were to never have money or fame again - I'd still have value in my soul, because I know that I can have an effect on someone else's life."
