Watch 'The Voice' Coaches Cover TLC's 'Waterfalls'

Alicia Keys, Adam Levine, Gwen Stefani and Blake Shelton make for quite the '90s cover.

Before season 12 of NBC's The Voice premieres next Monday (Feb. 27), Alicia Keys, Blake Shelton, Gwen Stefani, and Adam Levine come together for an acoustic version of TLC's 1994 classic "Waterfalls." 

With Shelton and Levine holding down guitar duty, Keys and Stefani anchor the track with their vocals. The ladies then team up to deliver a portion of late rapper Lisa "Left Eye" Lopes' verse. Once Stefani wraps up Left Eye's part, the quartet unite for a silky rendition of TLC's timeless chorus. Towards the end of the colorful jam session, Levine exuberantly shouts "I love that. That was it. Whatever that was, that was awesome. That's how you sing, America!"

Season 12 will mark Stefani's return to The Voice after missing the previous two, replacing Miley Cyrus. Last year, Paul Telegdy, president of Alternative and Reality Group at NBC Entertainment, revealed the show's decision to bring back Stefani, while also keeping Cyrus in the fold for season 13. 

"We can't wait to experience the unique chemistry and energy Gwen, Alicia, Blake and Adam will bring to season 12," he said in a statement to E!. "With Miley returning for season 13, we're truly ecstatic about the unmatched musical know-how and talent coming together in our coming seasons." 

Tune in Monday night (Feb. 27) at 8 p.m. ET for the premiere of NBC's The Voice and check out the cast's rendition of "Waterfalls" below.
