'The Voice' Season 6: Watch Adam Levine, Usher Sing Each Other's Hits (Video)
The Voice is continuing its tradition of kicking off the season with a performance by its coaches, but rather than having them all collaborate on a single song, they're taking each other's tracks for a genre-swapping spin on the same stage.
In a clip that NBC premiered during the Olympics on Thursday, Blake Shelton sings Shakira's English-language breakout, "Whenever, Wherever," with the Latin songstress joining him for the chorus. She then picks up her mic stand to rock out on "Boys Round Here," Shelton's hit with Pistol Annies & Friends.
Usher then emerges from among the audience, taking the lead on Maroon 5's "Love Somebody" as Adam Levine sings the harmony line. As all four join onstage, Levine launches into Usher's "Without You."
The Voice returns to NBC on Feb. 24 at 8 p.m. Until then, watch the video below:
