Cee Lo Green Confirms Christina Aguilera Duet

'Voice' coaches recording track for Aguilera's upcoming album.

We already know Christina Aguilera is hard at work on her upcoming album, and now we have confirmation that at least one of her fellow “The Voice” coaches will appear on the still-untitled set, due out later this year.

Talking to Billboard, Cee Lo Green revealed that he is working on a track with Aguilera, but declined to give much information about the song itself — other than it is happening and it is at least partly recorded.

“It’s a song for her album. I won’t disclose the title, because it could possibly be a working title,” Green said. “We’ve talked about it amongst ourselves, and I’m gonna go in on it and work it out. It’ll be the second song we’ve done.”

The first song they recorded together was the demo “Nasty,” which was recorded for but ultimately not included on the soundtrack to Aguilera’s film “Burlesque.”

“I just gotta get in there and … splash,” Green continued, implying that Aguilera already recorded her vocal for the unnamed track.

After a recent “Voice” taping, Aguilera told the show’s social-media correspondent Christina Milian that she has been hitting the studio in whatever free time she can find in her busy schedule with the TV hit. “I started [the album] whenever I started this show, and then [the show] kind of took off into this big thing,” Aguilera explained. “So, the show used to be a side project and kind of turned into a bigger time-fulfilling, dedicated project for me.”

The pop star, who appeared on Maroon 5′s #1 hit “Moves Like Jagger” last year, is working with a variety of producers and songwriters on the effort. “It’s just filled with fun and excitement, and it’s gonna come out later this year,” Aguilera added. “I’m very, very excited to share it with my fans, finally.”
