Zac Efron stars in the upcoming "Neighbors" movie in 2013. The "Parkland" actor goes shirtless in the film, showing off his yolo tattoo, abs and buff chest to fans.

According to People, the 25-year-old star plays the head of a frat house, who loves to flaunt his fit body and muscles.

The former "High School Musical" star stripped down for a new movie photo, where he is grilling food during a barbecue. It looks as if the young star has definitely been hitting the gym since his Disney days.

According to E! Online, the actor's hunky appearance is no surprise to anyone.

But his costar, Seth Rogen was shocked and thinks Efron is a very good-looking man.

"Zac Efron is incredibly handsome," Rogen said at an event in May. "I did a scene with him, and we were both shirtless, and it was a very humbling experience. I marveled at the fact that we were the same species."

The Universal Pictures film stars Efron and Rogen as neighbors who don't exactly get along. Rogen and Rose Byrne play the couple living next door to Efron in the comedy.

The highly anticipated movie hits theaters in May 2014.
