Around 2010, Aguilera announced the supporting concert tour for her sixth studio album, Bionic. At the same period, Aguilera was working on her film project, Burlesque. Thus, on May 24, 2010, Aguilera postponed the tour until 2011. In a message on her website and from tour promoter Live Nation, Aguilera stated that due to the excessive promotion of the album and her then upcoming film debut, she felt she needed more time to rehearse the show and with less than a month between the album release and tour, it was not possible to create and perform a show at the level that her fans expect from her.
