People love Zac Efron so much that they've even started to creepily fall in love with his upcoming role as serial killer Ted Bundy. So when the actor posted a shirtless photo with his brother, you can probably guess the intense reaction.

The photo, which Efron posted for his younger brother Dylan's birthday, shows both men showing off their abs at the base of a picturesque waterfall.

"Happy birthday @dylanefron! Honestly, I never in my wildest dreams, would’ve thought that the little terror, devil, monster that was my little brother would turn into my very best friend," Efron wrote. "I’m so proud of the man you are today. Let’s save the world together - one waterfall at a time. Love ya little brother!"
