Twenty-one-year-old Demi Lovato's fame began when she was cast on 'Barney and Friends'. From the outside, she was all smiles; but even as she grew up in front of the camera, she was falling apart. As Demi entered adolescence, she was being bullied, and she struggled with bulimia, suicidal thoughts, substance abuse, and eventually secretly began cutting herself. Her career was taking off, but she bowed out of her world-wide tour and checked herself into rehab, which she successfully completed. She started the Lovato Treatment Scholarship program to help others with their illnesses.Demi has many accolades, including an MTV Video Music Award, twenty-five Teen Choice Awards nominations (14 of which she has won), four People's Choice Awards, one ALMA award, a Billboard Touring Award and several others.Outside of her work in the entertainment industry, Lovato is involved in philanthropic activity through charity work and various social and environmental causes. In May 2013 she was awarded for her dedication as a mentor to teens and young adults with mental health challenges at a National Children's Mental Health Awareness day hosted by SAMHSA in Washington.
