launching short-lived Asian and European legs of the tour in March 2013, performing five shows that month across the continents. Her journey through going on tour for the first time since she withdrew from her last tour to seek treatment was chronicled on the MTV television documentary special Demi Lovato: Stay Strong, which aired in March 2012 and showed exclusive behind-the-scenes footage from the tour and dealt with Lovato's treatment and recovery (she admitted years later to being dishonest about her recovery in the film, revealing she was in fact under the influence of cocaine while being interviewed about her sobriety). With the tour announcement, Lovato expressed excitement to launch the project and commented about the difference between tour and her promotional shows: "We're gonna do the same show, but a little bit different... better and bigger, and my fans just have to come check it out." She said in conversation with MTV News, "We were just experimenting with the show and trying to see how it all played out and give my fans something that will bait them in for the tour." Lovato also appeared on Z100's annual Jingle Ball with various artists. Singles "Skyscraper" was released as the lead single from Unbroken on July 12, 2011. The song was written by Toby Gad, Lindy Robbins and Estonian singer Kerli Kõiv and produced by Gad. The song peaked at number ten on the Billboard Hot 100 chart in the United States. Elsewhere, the song peaked at number 18 in Canada, number 9 in New Zealand, number 45 in Australia and at number 7 in the United Kingdom. The song was critically acclaimed by music critics, some of them praising Lovato's vocals and the inspirational lyrics. Lovato performed the song several times, including on the television series America's Got Talent, The Ellen DeGeneres Show and Dancing with the Stars. The song was officially certified platinum in the United States in April 2012. "Give Your Heart a Break" was released as the album's second and final single on January 23, 2012. It was originally announced that the album's second single would be "Who's That Boy" featuring Dev, but it was later scrapped due to Dev's pregnancy. "Give Your Heart a Break" was written and produced by Josh Alexander and Billy Steinberg. Lovato performed the song at MTV's New Year's Eve on December 31, 2011, and the People's Choice Awards on January
