It's unclear whose project it is, but one thing is certain: Phil Collins and Adele are working on new music together.

In an interview with Inside South Florida that was pointed out by Rolling Stone, Collins confirmed he was working on new material with the British singer.

"I've just started to work with Adele," the Genesis frontman said. "I wasn't actually too aware… I live in a cave, but she's achieved an incredible amount. I really love her voice. I love some of this stuff she's done, too."

Whether the music is for an Adele release, a Collins release, a collaboration or none of the above is unknown. Collins hasn't released an album of new material since 2002's "Testify," though he did put out a record of '60s Motown and soul tunes, "Going Back," in 2010. The vibe on that album would fit snugly with Adele, who last released a new album with 2011's "21."

Collins' work on new material follows the 2011 announcement he had retired from music. "I've decided I kind of missed that writing creative stuff, so I'm trying to get back into writing, and that's getting into a certain headspace and personal drive," he said.
