Jimmy Fallon turned the tables on “The Voice” coaches on Monday night and had them sing karaoke in front of his “Tonight Show” audience.
But it resulted in the country star performing “YMCA,” and Levine performing Britney Spears‘ “Oops, I Did It Again,” so it wasn’t stupid for fans enjoying the spectacle.
The duet round called for Williams and Fallon to perform Rob Base and DJ E-Z Rock’s “It Takes Two.”
As a grand finale, Stefani and Shelton sang Drake‘s “Hotline Bling” together, with Shelton only contributing the occasional “bling” to the song.
NBC’s “The Voice” is currently in its ninth season, which premiered on Sept. 21.
