Bionic is the sixth studio album by American recording artist Christina Aguilera. It was first released on June 8, 2010, by RCA Records (Sony Music). The eighteen-track album sees Aguilera collaborating with a new range of producers and songwriters including Tricky Stewart, Polow da Don and Samuel Dixon, each of whom have three producing credits on the album. The album incorporates several different musical styles including R&B, pop, electropop, and synthpop.
Bionic is Aguilera's first studio album in four years since Back to Basics (2006). Upon release in the United States, the album debuted at number three on the Billboard 200 albums chart with sales of 110,000 copies. It had mixed success in the United Kingdom, where it debuted at number one with the lowest single-week sales in eight years before registering the largest single weekly decline for a number one album in UK chart history. Upon release, the album received mixed reviews from most music critics, who were ambivalent towards its musical direction and Aguilera's lyrical persona.
The lead single from Bionic, "Not Myself Tonight", premiered on March 30, 2010 via Aguilera's official website. The song was officially released as a single on April 13, 2010, and charted within the top 40 in most countries. The second single, "Woohoo", featuring Trinidadian rapper Nicki Minaj, was sent to US rhythmic radio on May 18, 2010, and failed to make much of an impact, only charting at number seventy-nine on the US Billboard Hot 100, due to digital sales. The third and final single, "You Lost Me" was released on July 6, 2010. Aguilera promoted the album by doing a number of television appearances, and further planned to promote it on the 2010 Bionic Tour, which was canceled shortly after its announcement.
