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."
