Demi Lovato first appeared in an episode of Barney & Friends in 2004 before landing the role of Charlotte on the TV series As the Bell Rings three years later. In 2008, she became a familiar face in the Disney franchise as she was cast as Mitchie Torres in Camp Rock the movie, along with the Jonas Brothers. In the same year, she also started appearing on Disney 365 and later, reunited with the Jonas Brothers for Camp Rock 2: The Final Jam . Her stardom eventually led to her own series, Sonny with a Chance, where she played lead character Sonny Munroe. The show ran from 2009 to 2011.
Aside from being an actress, she is also a famous singer whose debut album Don't Forget has sold over 500,000 records in the United States and got certified Gold by RIAA.
Lovato, who is involved in extensive philanthropic activities, is no stranger to controversy. In 2011, she left the Jonas Brothers' Live in Concert tour in order to enter a treatment center and "seek medical treatment for emotional and physical issues she has dealt with for some time."
