Demetria Devonne "Demi" Lovato (born August 20, 1992) is an American singer-songwriter, musician and actress. She made her debut as child actress in Barney & Friends. In 2008, she came to prominence as a starring cast member in the television film Camp Rock. She signed to Hollywood Records the same year, and released her debut studio album Don't Forget in September. It has been certified Gold by the Recording Industry Association of America (RIAA). In 2009, Lovato was commissioned her own television series Sonny with a Chance. That year, her second album Here We Go Again became her first to debut to top the U.S. Billboard 200.
After the release of additional television films and their accompanying soundtracks in 2010, Lovato's personal struggles the following year sent her acting career into hiatus. Her third album Unbroken (2011) addresses several of her difficulties, notably her lead single "Skyscraper". Since 2012, Lovato has served as a judge and mentor on the American version of The X Factor. Her fourth album Demi (2013) was preceded by its lead single "Heart Attack".
