So, you can probably guess the reaction when Zac uploaded a picture with his brother, both topless and soaking wet. I'm sure that has absolutely nothing to do with why the post has almost three million likes.
Of course, Twitter began thirsting almost immediately.
Although some people were just surprised that Zac has a brother, which to be quite honest is disrespectful.
Have you not seen Dylan Efron's Instagram? Here's some sample content, which just so happens to have 69,000 likes. Nice.
I was born in November so can somebody tell me why it suddenly feels like my birthday?
Anyway, off track. HAPPY BELATED BIRTHDAY, DYLAN! And thank you for the gift Zac, you really didn't have to.
