Christina's hotly anticipated 4th studio album, Bionic, will be released on June 8th, 2010, following the unveiling of its fiercely energetic single “Not Myself Tonight,” and its visually stunning, sexually liberating music video. Bionic saw Christina collaborating with artists and co-songwriters like Nikki Minaj (whose presence was felt on the rhythmic pounding of "WooHoo"), Linda Perry (who penned and produced a gorgeous ballad named “Lift Me Up”), Sia, Tricky Stewart, Polow Da Don, Le Tigre, Hill & Switch, and Ladytron among others. The title Bionic reflects Christina's range as an artist capable of exploring every side of her personality and using her voice in ways never heard before. Or, in her own words, “I was able to explore and create a fresh, sexy feel using both electronic and organic elements with subject matter ranging from playful to introspective. I am so excited for my fans to hear the new sound. It is something I don’t think anyone will expect.”
