Zac Efron decided to open up about pretty much everything when he sat down for a chat with The Hollywood Reporter, the "Neighbors" actor just so happens to be featured on the cover of the May 9th issue.

According to THR, during his chat with the magazine the 26-year-old opened up about his struggle with alcohol and drugs, his Skid Row experience and even ex-girlfriend Vanessa Hudgens.

The actor told the publication, "No matter who you are, you face challenges growing up," adding, "You go with your things, you learn, you have to. It's impossible to lead an honest and fulfilling life as a man and not make mistakes and 'fess up to them when you need to.

"But it's especially humiliating when they happen to be so public and so scrutinized. When you have success young, and you accept the good things, you have to accept all of it. You have to accept the moments of glory but also a great responsibility.

"And that responsibility, to some degree, involves being a role model. At the same time, I'm a human being, and I've made a lot of mistakes. I've learned from each one."

Efron also reflected on his romances, and explained that the "the struggles of dating, of falling in love, of searching for love and being there for your friends when they need you.

"There's no question that to receive anything great, like love or respect, or to better yourself, you have to give a piece of yourself away."

The "High School Musical" alumni admitted that although he is no longer in touch with ex-girlfriend Vanessa Hudgens, she is a "really interesting, sweet person."

Zac Efron also talked about the time he was punched in the face in downtown Los Angeles.

He explained, "I had a friend come pick me up late at night-we were looking for a place downtown to get a bite and catch up.

"We were having trouble finding somewhere...and the car ran out of gas off the 110. It was ridiculous. We had to pull over, and I called Uber [car service]."

While waiting, Efron said, "A homeless guy, or vagrant, tapped on the driver's-side window. Before I knew it, [my friend] was out of the car, and they started fighting.

"I saw that [the homeless man] was carrying some sort of a knife, or shank, and I got out of the car to disarm him. At some point, he dropped the knife, and I got hit pretty hard in the face-and almost instantly the police were there to break up the fight."

Halston Sage's rumored boyfriend who spent some time in rehab last year has since joined Alcoholics Anonymous and also has been seeing a therapist.

He admitted, "I just started going," adding, "And I think it's changed my life. I'm much more comfortable in my own skin. Things are so much easier now."

However, he confesses, "It's a never-ending struggle."

Despite his struggles Zac Efron revealed that he is happier than ever. He explained, "Without those moments where you feel like your lowest, it's impossible to appreciate the high ones."

He continued, "But I sit here in front of you today much happier and healthier than I've probably ever been."
