"I've been through a lot since the release of my last album, being on ('The Voice'), having had a divorce," she said. "This is all sort of a free rebirth for me."
Her new album's first single, "Your Body," was produced by Max Martin, who also produced Aguilera's last hit, the Maroon 5 smash "Moves Like Jagger," where she was featured.
"I'm embracing many different things, but it's all feel-good," she said of the album's material, including tracks that are "super expressive" and fun, with moments that are "super vulnerable."
"In the fashion that I always like to put forth, it's very self-expressive and it's all heartfelt," Aguilera said of her new material.
