Nothing screams TGIF like a live cover of TLC’s 1994 hit “Waterfalls” sung by "The Voice" Season 12 coaches Alicia Keys, Adam Levine, Gwen Stefani and Blake Shelton.

Holy harmony.

In the video, all four had the chance to sing solo verses, starting with Stefani. (Anyone else notice the way Shelton looked at her?) Levine and Shelton played acoustic guitar and Keys was on Rhodes piano. The eclectic group of voices provided for one glorious chorus.

Hands down best part: Stefani and Keys taking turns spewing Lisa “Left Eye” Lopes’ rap verse.

"I love that," Levine said when the song wrapped. "That was it. Whatever that was, that was awesome. That's how you sing, America!"
