Demetria Devonne "Demi" Lovato (born August 20, 1992) is an American actress and singer who made her debut as a child actress in Barney & Friends. In 2008, Lovato rose to prominence in the Disney Channel television film Camp Rock and signed a recording contract with Hollywood Records. She released her debut album, Don't Forget, that September; it has been certified gold by the Recording Industry Association of America (RIAA) for sales of over 530,000 copies. In 2009 Lovato received her own television series, Sonny with a Chance. That July her second album, Here We Go Again, debuted at number one on the U.S. Billboard 200; its title track became her first single to break the top 20 of the Billboard Hot 100, reaching number 15.
After the release of additional television films and their soundtracks in 2010, Lovato's personal issues put her career on hiatus and ended Sonny with a Chance after its second season. Her third album, Unbroken (2011), addresses several of her difficulties. Its lead single, "Skyscraper", became Lovato's first single to be certified platinum in the United States; its second single, "Give Your Heart a Break", was certified double platinum. Lovato was as a judge and mentor on the American version of The X Factor in 2012 and 2013. Her fourth album, Demi (2013), had first-week sales of 110,000 copies (the best debut week of Lovato's recording career). Demi was preceded by its lead single, "Heart Attack" (certified double platinum in the United States), that February. In September 2013 Lovato announced plans for a North American leg of her third headlining concert tour, the Neon Lights Tour, to promote Demi. In May 2014 (shortly after the tour) Lovato announced her fourth concert tour, the Demi World Tour, also in support of Demi. This would mark Lovato's first world tour.
