Gwen Stefani Sings Hotline Bling Karaoke On The Tonight Show

she know when that hotline bling

Credit The Tonight Show braintrust, who came up with yet another highly watchable game called Spin the Microphone, which they tested out last night on the coaches from The Voice. Basically, you spin a microphone around, and whoever it lands on has to perform a karaoke song, or make another person do it.

We're not sure what Adam Levine was thinking when he half-assed "Oops...I Did It Again." Blake Shelton doing "Y.M.C.A." was the embodiment of meh, and Pharrell and Jimmy Fallon doing "It Takes Two" should have been saved for the next edition of The History of Rap. But then it was Gwen Stefani's turn to sing "Hotline Bling"—which she was very excited about—and she killed it, because killing it is what Gwen Stefani does.
