Within a few short years, American musician, author, and actor Demi Lovato went from a Disney hopeful to a chart-topping pop star known for their spunky, confident air. A child actor who appeared on segments of Barney & Friends and As the Bell Rings in the 2000s, they had a breakout year in 2008 with a starring role in the Disney Channel movie Camp Rock and a debut single, "This Is Me" featuring Joe Jonas, that became a Top Ten hit in the States. Released the same year, their debut album, Don't Forget, went to number two on the Billboard 200, only to be outdone by the follow-up, 2009's Here We Go Again.
