Cancelled concert tour Aguilera initially planned to further promote the album by embarking on The Bionic Tour. It was announced in early May 2010 that twenty shows had been scheduled in North America, which would run from July 15, 2010, to August 19, 2010. British singer
Leona Lewis was said to be a supporting act and the tour would be in conjunction with North American leg of Lewis's tour
the Labyrinth (2010). Later that month, Aguilera announced that she would postpone the tour until 2011, however, that never happened. In a message from tour promoter
Live Nation, Aguilera stated that due to the excessive promotion of the album and her then upcoming film debut in
Burlesque, she felt it was necessary to take more time to rehearse the show and with less than a month between the album release and the tour, it was impossible to create a show as her fans' expectation.
Singles was featured on "Woohoo", which was released as the second single in the United States and several European countries "
Not Myself Tonight" was released as
Bionics
lead single on April 2, 2010. It debuted and peaked at number twenty-three on the US
Billboard Hot 100, becoming Aguilera's third highest solo debut on the chart after "
Keeps Gettin' Better" (2008) and "
Ain't No Other Man" (2006). Internationally, the song was a moderate commercial success, peaking at number twelve in the United Kingdom, and within the top forty in Australia, Austria, New Zealand and Sweden. The song received generally positive reviews from music critics, who complimented its club nature and Aguilera's vocals on the track; some reviewers also referred to it as her best uptempo recording since her single "
Dirrty" (2002). The accompanying
music video, directed by
Hype Williams, featured a
S&M theme with Aguilera sporting different bondage-inspired looks. Paying homage to
Madonna's music videos for "
Express Yourself" (1989) and "
Human Nature" (1995), the video received mixed reviews from critics, who complimented its aesthetic but called it unoriginal. "
Woohoo", featuring rapper
Nicki Minaj, was released as the second single from
Bionic. It was made available exclusively to the
iTunes Store on May 18, 2010 before being serviced to
rhythmic contemporary radio on May 25, 2010. The song peaked at number one-hundred-and-forty-eight on the
UK Singles Chart due to high digital sales, but was never released as a single there. It received generally favorable reviews, with critics praising Minaj's appearance in the song and commending Aguilera's powerful vocals. "

contemporary hit radio on June 29, 2010, in the United States. Leah Greenblatt from
Entertainment Weekly called "You Lost Me" a "lovely" ballad and Amber James said the song was a "somber track" that brings the "honesty and emotion that have made Aguilera one of the premier balladeers of our time." "
I Hate Boys" was released as the fourth single digitally on September 3, 2010 in a two-track single format. It was the eighth most-added song to radio stations in Australia from the week ending July 23, 2010. It peaked at number twenty-eight on the
