While the sexy actor looks like he could be 17 Again, his latest characters tell a different story. This year alone, he took on the roles of a post-grad finally learning to grow up in Neighbors 2, a put-together prepster who was preparing for his wedding in Dirty Grandpa, and a rowdy party boy desperately searching for a plus one in Mike and Dave Need Wedding Dates.
Next year promises to be Efron's biggest yet, with roles lined up in the much-anticipated Baywatch reboot and the star-studded comedy The Masterpiece. Plus, the 29-year-old will take a turn for the dramatic in the biographical musical, The Greatest Showman on Earth, a new film about P.T. Barnum, the founder of the Ringling Bros. and Barnum & Bailey Circus.
In honor of Efron's joyous occasion, relieve 13 of his best Instagram moments, including the time he revealed to the world how two Efrons are better than one. Happy birthday, Zac!
When he painted his nails for a cause:
Thanks for the nom, @chrishemsworth. Happy to paint one nail and be a @PolishedMan this month to say no to violence against children. 1 in 5 children are subject to physical and/or sexual violence before the age of 18 and that’s one too many. Find out how you can help/donate at http://polishedman.com. I nominate the following studs @james_marsden, @thehughjackman, @andybovine, @ders808, @blakeanderson and @deandrejordan6 to become a #polishedman. #nailittoENDit
