Efron's 'Mike and Dave Need Wedding Dates' co-star turned 33 on Monday.

Actor Adam Devine turned 33 on Monday, and his Mike and Dave Need Wedding Dates co-star Zac Efron made the event memorable by wishing 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 f—ing dude."
