Joe Jonas has revealed all in a detailed and intimate, first-person New York profile.

In addition to discussing the fact that his solo album 'Fastlife' tanked and why the Jonas Brothers went on 'GMA' to detail their breakup, he also offered his theory as to why Disney stars rebel and get crazy. He shared that it was Demi Lovato and Miley Cyrus who introduced him to pot and that his romantic relationship with Lovato attracted more attention than he was comfortable with.

He really pulled back the curtain on the pressures that Disney kids feel and what it's like to be a famous teenager with a multi-million dollar brand to protect.

Jonas, who says that he is not religious but has a relationship with God, first spoke about his coupling with Lovato. The serial dater said:

One relationship that meant a lot to fans was the one I had with Demi Lovato, who I’ve known for years. We had been friends forever, we were both Disney kids, and because we played a couple in the Camp Rock Disney Channel specials—and fans liked seeing us together—we eventually dated for a month. I really got to know her and got to see the ins and outs of what she was struggling with, like drug abuse. I felt like I needed to take care of her, but at the same time I was living a lie, because I wasn’t happy but felt like I had to stay in it for her, because she needed help. I couldn’t express any of that, of course, because I had a brand to protect.

Things eventually came to a head.

Demi ended up punching a girl in the face on a plane, because she thought the girl was blaming her for something. Everybody gasped, and the girl just started bleeding. That’s when her team and her family told her, 'You need to go into rehab.' I remember being in South America, and fans immediately jumped to the conclusion that we kicked her off the 2010 tour, and they just hated on us for it.

His intro to marijuana came courtesy of his fellow Disney divas.

The first time I smoked weed was with Demi and Miley. I must have been 17 or 18. They kept saying, 'Try it! Try it!' so I gave it a shot, and it was all right. I don’t even smoke weed that often anymore. I was caught drinking when I was 16 or 17, and I thought the world was going to collapse. But I was in another country, and it was legal there. My 21st birthday, I fell down a flight of stairs. I was unconscious that time, and my whole team was scared to death that somebody was going to get a picture. Now I appreciate wine or a vodka-soda at the end of the day every once in a while.

The singer also offered his theory about why Disney stars grow up and ditch their clean-cut images. "Being a part of the Disney thing for so long will make you not want to be this perfect little puppet forever," he explained. "Eventually, I hit a limit and thought, 'Screw all this, I’m just going to show people who I am.' I think that happened to a lot of us. Disney kids are spunky in some way, and I think that’s why Disney hires them. 'Look, he jumped up on the table!' Five, six, 10 years later, they’re like, 'Oh! What do we do?' Come on, guys. You did this to yourselves."

He revealed that he lost his virginity at age 20 -- so he smoked pot before he had sex-- and referred to his relationship with 'Twilight' actress Ashley Greene as his first serious romance. "After Ashley, I took two or three years to just be single," he said. "I was hooking up and having fun. Now I’m with someone I really care about. We get each other." He also admitted to dating fans.

While Joe Jonas spilled about his past, he is looking ahead to the future.

Now that I’m 24 and have control of my life, I’m going back to the drawing board. I’ve been through a s--t-ton of stuff, but I’m genuinely excited because now I can go back to the studio with those people who I used to work with. I don’t have to rely on anyone else’s opinion, whether good or bad, and hear them say, “No, no, you can’t go write with them. That’s too weird for us.” Because weird works. Look at Lorde.

Onward and upward for Joe Jonas.
