Gwen Stefani, Blake Shelton And Alicia Keys Cover 'Waterfalls'

(Radio.com) Gwen Stefani and Alicia Keys will be returning to The Voice as Season 12 coaches, and ahead of the show's debut they teamed up with their fellow coaches to cover TLC's hit "Waterfalls."

Shelton plays guitar while Keys plays, what else, keys. Each singer, known for a different style, puts their individual stamp on the verses, but they come together on the chorus for a harmony-infused collaboration.

The acoustic cover shows that even while the four coaches may be playing against each other on the show, they can put their competitive side to rest for a song. Check it out here.
