Zac Efron Wishes Adam Devine Happy Birthday With an Awesome Song: Watch

Actor Adam Devine turned 33 on Monday (Nov. 7) and his Mike and Dave Need Wedding Dates co-star Zac Efron wished him happy birthday with an original song on Twitter. 

Sitting behind a grand piano, Efron showed off his musical chops playing a blues riff embellished with some showy flourishes. In the made up joke song, he sang in a soulful tenor, "Happy birthday to one hell of a sexy dude. Oh happy birthday to one hell of a cool dude. Oh, I said happy birthday Adam Devine because you're the best, the best, the coolest fucking dude."
