Zac Efron shows us his banging hot younger sibling!

Cape Town - We always knew Zac Efron's younger brother was turning out to be a little hottie, but we weren't ready for the pic he posted with his younger brother.

Dylan Efron clearly proves that he isn't the only good looking sibling in the family nor the only one who looks hot without a shirt on...

Introducing the hot shirtless and very chiselled Efron brothers...

And it seems Dylan looks up to his big bro. Zac recently found a poem his brother wrote about him in the 6th grade.

Aww, we love brotherly love:
