"Bangerz" was additionally promoted through the documentary "", which premiered through MTV on October 2; it covered the production of the project and the lead-up to its release. In November, Cyrus traveled to Europe again to sing both "We Can't Stop" and "Wrecking Ball" at the 2013 MTV Europe Music Awards in Amsterdam on November 10; she garnered media attention for smoking a joint of marijuana on-stage while accepting the Best Video Award for the latter single. During her trip, she also performed "Wrecking Ball" on "Wetten, dass..?" in Germany (November 9), BBC Radio 1's Live Lounge in London (November 12), and the 2013 Bambi Awards in Germany (November 14). On November 17, she performed "Wrecking Ball" on "The X Factor" in London. After being criticized for delivering a lackluster vocal performance, Cyrus was placed under "vocal rest" by her doctors in preparation of the Bangerz Tour. On November 24, Cyrus performed "Wrecking Ball" at the 2013 American Music Awards; a digitally animated cat projected on the screen behind her lip-synced the lyrics alongside Cyrus. In December, she performed at Jingle Ball concerts in Los Angeles (KIIS-FM Jingle Ball), Saint Paul, Atlanta, New York City, Washington, D.C., Tampa and Sunrise. She was expected to perform in Boston during the series, although her flight from New York City was cancelled due to Winter Storm Electra and was therefore unable to attend.
