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.
