Demi Lovato's fame began when she was cast on Barney and Friends in 2002. From the outside, she was all smiles, but as she grew up in front of the camera—the star of the record-breaking Camp Rock franchise; leading lady of her own Disney show, Sonny with a Chance; and a budding music career—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.

She appeared as a judge on X-Factor, and her album Demi (2013) went platiumum. Confident, Lovato's fifth studio album, was released in 2015, and Tell Me You Love Me was released in 2017 and featured "Sorry Not Sorry," Lovato's highest charting song in the US. Demi has many accolades, including two Grammy nominations, one MTV Video Music Award, five People's Choice Awards, twenty-five Teen Choice Awards nominations, 14 of which she has won, one ALMA award, a Billboard Women in Music 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.
