Zac Efron is generally a good looking guy but the actor is especially hot when he is shirtless. Well, fans looking to see the 26-year-old flaunting his perfect abs will love his new movie "Neighbors" in which he plays a hard-partying frat boy.

According to E! News, while at the film's premiere at the South By Southwest (SXSW) Fesitval in Austin the star admitted that he's shirtless "a lot" in the film.

He explained, "I don't know how many times. It just seemed like whenever we felt like it-no hesitation," adding, "It was like wake up, work out and then go to set and party all day."

In "Neighbors" Zac Efron stars alongside Seth Rogen and Rose Byrne who play a young couple with a baby that get new neighbors who just happen to be a rowdy fraternity house.

The "That Awkward Moment" actor plays the fraternity president leading the group of trouble-making frat brothers that consist of Dave Franco, Christopher Mintz-Plasse and Jerrod Carmichael.

While on set Lily Collins' ex-boyfriend, Zac Efron made sure that he stayed fit and decided to workout between scenes. The actor even found a spot on set where he thought no one could see him doing a "ton of pushups." However, someone was watching him.

The "Parkland" actor revealed some details about the old man, "He goes, 'Steve McQueen used to do that,'" adding, "He just looked like he had a lot of wisdom and I was like, 'Really, Steve McQueen did that?' He's like, ''Yeah, I saw him do that,' and then he goes, 'Don't do too many because you'll get sweaty.'"

Another interesting experience on set was Seth Rogen's shared shirtless scenes with Efron. The comedian described standing next to the young star.

He confessed, "It was brutal," adding, "I was just telling my wife there are a few scenes where he had his shirt off and people make a noise I've never heard before when they see him. It's crazy. It's a weird noise."

Zac Efron got his big break in the hit Disney movie "High School Musical" alongside ex-girlfriend Vanessa Hudgens.
The actor mentioned that the cast has been considering a reunion. He admitted, "We're all thinking about it," adding, "I continue to see all the guys from High School."
