The duo faced off on The Tonight Show With Jimmy Fallon, with Jimmy Fallon chiming in during the face off as well.
Blake kicked off the 'Lip Synch Battle' with "Puttin' on the Ritz" by Taco, palming a glass of champagne. Before the song was done, the country crooner took his first performance of the night up a notch with a tap dance number.
Jimmy soon followed with his own soulful (and hilarious) interpretation of Ellie Goulding's "Burn." Meanwhile, Gwen was up next faux crooning Carly Rae Jepsen's "Call Me Baby" in a gold sequin vest, adding in some classic No Doubt moves - including a hip roll on Jimmy.
Check out the trio performing those songs, plus Gwen and Blake stealing the show (and the lip synch battle title) when they lip synched Diana Ross and Lionel Richie's "Endless Love" in their own unique way.
