It's hard to say who's hotter in this pic of Zac Efron and his younger brother Dylan.
This wouldn't be the first time we've gushed over the Efron boys. This past May, Zac shared a poem that Dylan penned about his famous sibling for an old homework assignment. The poem was titled "A Brotherly Thing."
"My brother is a movie star, and is only 16," Dylan, who's now in his early 20's, wrote. "He doesn't have a job yet. Still, he thinks he is the queen."
Showing love for his older brother, Dylan added, "I guess he isn't that bad, if I think about it twice. He helps me with my homework, and always gives advice."
Who do you think is hotter: Zac or Dylan?
