Zac Efron and Adam Devine have a beautiful bromance!
On Monday, the Pitch Perfect actor turned 33 years old, and the High School Musical alum decided to do something super special for his pal!
The A-lister tapped into his inner Troy Bolton, and took to Twitter to serenade his Mike and Dave Need Wedding Dates costar with an original birthday blues song!
The gorgeous guy sat behind a piano, belting out:
"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*cking dude."
