America’s favorite twink heartthrob morphed into a twunk a while ago, but now that he’s celebrating 31 years he’s older, wiser and hotter than ever, time to take another look at his birthday suit.
Zac Efron has been a teen heartthrob since he made his debut in the Disney Channel’s spectacularly successful tween franchise High School Musical.
Since then there have been plenty of ASStastic moments and our friends at Mr. Man are here to cover them all.
We’re showing some of our favorites here but you can always see more Zac and his perfect butt in their Hollywood’s Hottest Butts playlist.
From “17 Again” where he’s young and shirtless and serving you TigerBeat realness to “Dirty Grandpa” where he’s naked AF and showing his cakes – we love it all.
Of course, we also love jacked Zac from Baywatch and Neighbors 2 – so plump and juicy. We’d love to squeeze those melons.

But when it comes down to it, we must admit, our favorite Zac is naked Zac on the toilet in “That Awkard Moment.” Does that make us dirty?
Meanwhile, someone who is both a bigger Photoshop dork than I am – and has a lot more, errr, time on his or hands, did a little digital magic with Zac Efron from “Dirty Grandpa” and had him waking up next to someone else’s morning wood …
Happy Birthday, Zac! Many, ma-n-y more!
love that he was born on my birthday
Zac could get naked on my face any day of the week.
And twice on the weekends.
NO ONE CARES
You are speaking for yourself. Love me some Zac! Happy Birthday, Cutie!
