Demetria Devonne "Demi" Lovato (born August 20, 1992)is an American actress and singer. She made her debut as a child actress in Barney & Friends. In 2008, she came to prominence as a starring cast member in the Disney Channel television film Camp Rock and signed a recording contract with Hollywood Records. Lovato released her debut studio album Don't Forget that September; it has since been certified gold by the Recording Industry Association of America (RIAA) for sales of over 530,000. In 2009, Lovato was commissioned her own television series, Sonny with a Chance. That July, her second studio album Here We Go Again became her first project to debut 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 after reaching number 15.
After the release of additional television films and their accompanying soundtracks in 2010, Lovato's personal struggles sent her acting career into hiatus, and saw the closure of Sonny with a Chance after its second season. Her third studio 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, while the second single "Give Your Heart a Break" was certified double-platinum in the country. Lovato served as a judge and mentor on the American version of The X Factor from 2012 through 2013. Her fourth studio album Demi (2013) opened with first-week sales of 110,000 copies, and in doing so became the best-selling debut week of Lovato's career. It was preceded by its lead single "Heart Attack" that February, which was certified double-platinum in the United States. In September 2013, Lovato announced plans to go on a North American leg of her third headlining concert tour, The Neon Lights Tour in promotion of Demi. In May 2014, shortly after the closing of "The Neon Lights Tour", Lovato announced her fourth headlining concert tour, The Demi World Tour, also in support of her fourth studio album Demi. This would mark Lovato's first ever world tour.
Throughout her music career, Lovato has embarked on several concert tours. In 2008, she served as the opening act for the Jonas Brothers' Burnin' Up Tour and Avril Lavigne's Best Damn Tour. Later that year, she embarked on her first promotional tour, the Demi Live! Warm Up Tour. Since then she has held two headlining concert tours, Demi Lovato: Live in Concert and A Special Night with Demi Lovato. Her work has additionally earned several accolades, including one MTV Video Music Award, twenty five Teen Choice Awards nominations, eleven of which she has won, four People's Choice Awards, one ALMA award, a Billboard Touring Award and several others. In 2013, Maxim ranked her 26th on their Hot 100 while Billboard ranked her second on their Social 50 Artists of the Year. Outside of her work in the entertainment industry, Lovato is involved in philanthropic activities through charity work and various social and environmental causes. In May 2013, she was awarded 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.
