Which Team Had the Best Duet of the Night on The Voice, May 7?

Last night, the Final 4 contestants had the opportunity to perform one song of their choosing, one of their coach's original songs, and a duet with their coach.

It was a rare opportunity for the coaches to get on stage and support their contestants as performers and equals.

Adam Levine and his contestant Tony Lucca sang a beautiful rendition of The Beatles' “Yesterday" that seemed like the perfect blend of their voices.

Fulfilling a lifelong dream, Chris Mann sang “Prayer” with his coach Christina Aguilera. The power of her voice combined with his vocal precision made for a superb blend.

Though their respective genres are drastically different, Blake Shelton and his finalist Jermaine Paul tore up the stage with their high-energy rendition of “Soul Man.”

Further proving that they’re kindred spirits, Cee Lo Green and rocker Juliet Simms took to the stage on motorcycles to sing “Born to Be Wild.”

But which duo had the best duet of the night? Vote below!
