Even before she was bullied, before she became a role model for victims of schoolyard tormentors and those struggling with mental illness, songstress Demi Lovato knew she wanted to give back. From age seven, she says, "I knew I had a purpose." Now, at 20, as an official Ambassador for We Day and Free The Children, Lovato has been busy making a difference. Her recent appearance on a celebrity edition of The Price Is Right earned almost $50,000 for Free The Children. And she just launched Demi Lovato's Charity Boutique on eBay, with 100 per cent of the proceeds going to help children in developing communities around the world.

Lovato is auctioning off some big labels, with dresses from the U.K.-based label Temperley London and American designer Alexander Wang, a motorcycle jacket by Phillip Lim and a few Topshop pieces. You can shop in Lovato's closet for a good cause here.
