In 2007 and 2008, Lovato played Charlotte Adams on the Disney Channel short series As the Bell Rings.

Warm Up Tour before the release of her debut album and appeared on the Jonas Brothers' Burnin' Up Tour.

The album debuted at number two on the Billboard 200, with first-week sales of 89,000 copies. Ten of its songs were co-written with the Jonas Brothers.  Don't Forget was certified gold by the Recording Industry Association of America (RIAA) for US sales of over 500,000 copies. Its lead single, "Get Back", was praised for its pop rock style and peaked at number 43 on the US Billboard Hot 100, selling over 560,000 copies in the United States. The album's second single, "La La Land", was cited for its strong rock elements and peaked at number 52 in the US, and cracked the top 40 in Ireland and the United Kingdom.
