Zac Efron Takes His Bromance With Adam Devine to the Next Level

Zac Efron and his Mike and Dave Need Wedding Dates co-star Adam Devine definitely have a super cute bromance going on and Zac took things to the next level for Adam‘s b-day!

The 29-year-old actor decided to pen an original song for Adam and took to his Instagram to share it with the world…and show off his #pianoskills!

“Happy birthday to one hell of a sexy dude…Cause you’re the best, the coolest mother f***king dude!” Zac hilariously sang.

In the caption he added, “Happy Birthday @andybovine. This one is for you. #PianoSkills.”
