Zac Efron Posts Shirtless Selfie with Hot Younger Brother Dylan Efron

A Shirtless Zac Efron
Zac Efron is looking very buff these days and is not afraid to show it off.

What is better than one shirtless Efron brother? Two shirtless Efron brothers!

Actor Zac Efron posted a picture of himself to Twitter showing off his shirtless self and while he’s sticking out his tongue, all the while riding on top of his shirtless younger brother Dylan’s back (who has grown up fast).

If you recall, a few months ago Zac tweeted a poem his brother Dylan wrote in 6th grade about Zac.

The silver screen heartthrob has been busy filming the movie Mike and Dave Need Wedding Dates alongside Adam Devine, Anna Kendrick and Aubrey Plaza in Oahu, Hawaii. Efron and Devine play brothers in the film who buy personal ads to find a pair of dates to be their guests at a wedding.
