The 29-year-old actor took to his Instagram to wish his Mike and Dave Need Wedding Dates co-star a happy birthday in the form of a performance of a super funny original song.
“Happy birthday to one hell of a sexy dude…Cause you’re the best, the coolest mother f***king dude!” Zac sang, while also playing the piano.
“Happy Birthday @andybovine. This one is for you. #PianoSkills,” he captioned the cute video.
