Christina Aguilera has been working on a new album
With more than a decade in the music business behind her, the album will be a culmination of "everything I've experienced up until this point," the 31-year-old said.
"I've been through a lot since the release of my last album," she said. "This is all sort of a free rebirth for me."
The Burlesque star and Jordan Bratman were married for five years before she filed for divorce in 2010. They have a four-year-old son, Max.
Her new album's first single, Your Body, was produced by Max Martin, who also produced Christina's last hit, the Maroon 5 duet Moves Like Jagger.
"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".
The new record, which is without a release date or announced title, will feature fellow US Voice coach Cee Lo Green and comes two years after Christina's lacklustre Bionic, which has sold 310,000 units, according to Nielsen SoundScan. That album featured electronic and dance-flavoured tracks as well as pop ballads. It's her only album to not reach platinum status.
"In the fashion that I always like to put forth, it's very self-expressive and it's all heartfelt," Christina said of her new material.
Adam Levine, Maroon 5 frontman and also a Voice coach, told Christina at a recent news conference for the show that he'd heard Your Body and added, "I hate you because it's so good."
Christina will perform the song on NBC's The Voice on September 17. The US show's third season starts on September 10.
