Demetria Devonne "Demi" Lovato (born August 20, 1992) is an American actress, singer, and songwriter 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. Her second album, Here We Go Again, was released that July and 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, and being certified platinum. 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 at the time to be certified platinum in the United States; its second single, "Give Your Heart a Break", was certified triple 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 triple 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. A total of four singles were released from Demi, including "Made in the USA", "Neon Lights", which was certified Platinum in the US, and her latest single "Really Don't Care". During her musical career, Lovato has made a number of concert tours. In 2008, she was the opening act for the Jonas Brothers' Burnin' Up Tour and Avril Lavigne's Best Damn Tour. Later that year Lovato began her first promotional tour, the Demi Live! Warm Up Tour. Since then, she has headlined four concert tours: Demi Lovato: Live in Concert, A Special Night with Demi Lovato, The Neon Lights Tour, and the Demi World Tour. Lovato has received a number of accolades, including an MTV Video Music Award, thirty one Teen Choice Awards nominations (twelve of which she won), five People's Choice Awards, two ALMA Awards and a Billboard Touring Awards. In 2013, Maxim ranked her 26th on its Hot 100 list and Billboard ranked her second on its Social 50 Artists of the Year list. Outside the entertainment industry, Lovato is involved with several social and environmental causes. In May 2013, she was cited for her dedication as a mentor to teens and young adults with mental-health challenges at a National Children's Mental Health Awareness Day hosted by the Substance Abuse and Mental Health Services Administration in Washington, D.C.. She has also become an advocate for the LGBT community. In 2014 she was announced as the Grand Marshal for LA PRIDE week, and that same year she became the face for HRC's America's for Marriage Equality Campaign.
