Christina Aguilera collaborated with fellow The Voice coach Adam Levine on Maroon 5’s “Moves Like Jagger” last year. She’ll be joining forces with Cee Lo Green next.

Aguilera told fans about the upcoming collaboration with Green before Tuesday’s episode of The Voice, also revealing that her next album would take time as she’s looking for “personal” songs.

Cee Lo didn’t want to reveal too many details, but spoke to Billboard after Tuesday’s show.

“It’s a song for her album. I won’t disclose the title, because it could possibly be a working title,” he said. “You know, but 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 pair had previously worked on “Nasty” together – an unreleased song originally for the soundtrack to Burlesque.
