The 26-year-old actor was reportedly punched in the mouth Sunday night after he and a body guard got into an argument with a few of the homeless individuals in downtown L.A., according to TMZ.

The website reported that Efron told authorities at the scene that they had thrown a bottle out the window of his car while waiting for a tow truck after running out of gas. 

Apparently, the homeless people saw this as a threat, and confronted Efron. According to him, two of them attacked his bodyguard when he got out of the car to help, thus ensuing the hit to the pretty face. 

"It was the hardest I've ever been hit in my life," Zac said.

Back in November, Efron broke his jaw saying he slipped on a pool of water in his home. He's also been in rehab twice last year for cocaine abuse. One source reported that Efron was "obviously intoxicated."

Law enforcement said no one was arrested because they viewed it as "mutual combat." 

Let's just hope the actor learns a lesson from getting clocked in the face.
