Throughout the sequel, we're lucky enough to be serenaded by Perez's beautiful voice. And if you're wondering if that really was him singing and playing the guitar, the answer is yes! Perez grew up singing in musical theatre, and in an interview with POPSUGAR, the actor revealed that he learned how to play guitar for the role. "I practiced my butt off," he said. "Looking at those strings, I was very confused the first couple of weeks. And then it just kind of became like muscle memory."
