After the release of additional television films and their accompanying soundtracks in 2010, Lovato's personal struggles sent her acting career into hiatus. Her third album Unbroken (2011) addresses several of her difficulties, notably her lead single "Skyscraper" which became her first single to go Platinum in the United States. The second single from the album "Give Your Heart a Break" became a breakout song for Lovato, becoming her biggest radio hit at the time and being certified 2x Platinum in the United States. 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" which broke new ground again, going 2x Platinum in the US and becoming her first international hit in countries such as the UK, debuting and peaking at number 3 in its first week.
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 she was also named 26th on Maxims Hot 100, and 2nd on Billboards 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 SAMHSA in Washington.
