Nick Jonas sent fans into frenzy during his performance at the Cannes amfAR Gala when he brought out Joe Jonas for a surprise Jonas brother concert. The youngest Jonas brother, 31, was scheduled to perform at the event held on Thursday, May 23. The 34-year-old Jonas Brothers frontman, however, was not.

Of course, that didn’t stop him from joining Nick on stage. In a video shared by Diplo to his Instagram, Joe could be seen in the audience as Nick asked from the stage, “Joe, where you at?” Diplo then handed a microphone to Joe who then started walking towards the stage as the backing tack for his song, Cake By The Ocean , started playing. “Ladies and gentlemen, give it up for Joe Jonas!” Nick announced as Joe joined him on stage.

As the brothers – sans Kevin – hyped up the crowd, Nick noted, “This looks exactly like a Jonas Brothers concert.” Before Joe’s surprise appearance, Nick also performed his 2014 hit Jealous as well as Frankie Valli’s Can’t Take My Eyes Off You . Joe gave absolutely no indication that he would also be performing, save for an Instagram snap of Nick gazing out a window from Hotel du Cap-Eden-Roc.
