WATCH: "The Voice" Coaches Sing TLC's "Waterfalls"!

Ahead of the premiere of the 12th season of US Edition of The Voice, coaches Adam Levine, Alicia Keys, Blake Shelton and Gwen Stefani release a video of them singing an acoustic version of TLC's 1994 hit, "Waterfalls."

Aside from them singing on the track, the promo features both Adam and Blake on guitars while Alicia and Gwen take on rapping duties (which was originally done by the late Lisa "Left Eye" Lopes).  

"I love that. That was it. Whatever that was, that was awesome. That's how you sing, America," Adam ends the jam session.
