Listen to Jonas Brothers on iHeartRadio

Joe Jonas opens about the Jonas Brothers breakup - and his personal breakups - in a candid first-person New York magazine story.

The singer begins by alleging that the Disneymachine wanted to control every facet of his and his brothers’ lives.

“Being a part of a company like that comes with certain expectations,” says Jonas, who recalls undergoing intense media training and having a ban on anything remotely sexual, despite the temptations of a huge fan base made up of mostly girls.

“There were the moments when I’d walk into my hotel room only to find a girl I didn’t know standing there,” says Jonas. “We were kids working with Disney, so finding a girl in our hotel room didn’t feel like an open invitation.”

The performer eventually started to have secret rendezvous - sometimes with fellow famous stars, other times with fans themselves - and lost his virginity when he was 20 years old.

Jonas confesses, “I did other stuff before then, but I was sexually active at 20. I’m glad I waited for the right person, because you look back and you go, ‘That girl was batsh*t crazy. I’m glad I didn’t go there.’”

He doesn’t reveal who that “right person” was, but goes on to discuss his relationships with Demi Lovato and Ashley Greene.

Jonas acknowledges that his relationship with Lovato “meant a lot to the fans,” and during their short-lived romance, he saw first-hand the demons she was wrestling with, and says it turned into “an insane situation.”

“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,” he says.

Jonas labels Greene his “first serious relationship,” and blames “long distance” for their “difficult” split.

“After Ashley, I took two or three years to just be single. I was hooking up and having fun,” he says. “Now I’m with someone [Blanda Eggenschwiler] I really care about. We get each other.”

Not mentioned? Jonas’ ex Taylor Swift, though some fans are likely to read between the lines.

"I genuinely don’t have any resentment against any of my exes. So I’m not going to disparage anyone I was in a relationship with - only I might put it in my music a little bit, and hint at it, and tease it here and there, just enough for the fans and the people who really know the story,” he explains before adding, “But I’m not going to openly say, ‘Yeah, actually, this person is a b*tch, and she did this to me.’ I don’t feel the need to do that to sell records."

Jonas says he also experimented with drugs and alcohol behind closed doors.

“The first time I smoked weed was with Demi and Miley [Cyrus]. 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,” he recounts. “I was caught drinking when I was 16 or 17, and I thought the world was going to collapse.”

“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,” he reveals.

Jonas goes on to admit that “the Jonas Brothers’ breakup was going on for a lot longer than a lot of people thought.”

“We hit a place where we just weren’t jelling on the same things,” he says.

And even though he and his brothers disagreed about the future of their music, Jonas says he “freaked out” at the idea of calling it quits.

“I didn’t know whether to pick up and leave or just punch something, because I was furious,” the star recalls. “I’d spent so long working with my brothers on this band, and in my mind, it felt like we were just giving up. It didn’t make sense to me.”

He adds, “But once I started peeling back the layers, I understood. There were a lot of dysfunctional things going on… I didn’t care about the money; I just wanted to figure out the right, healthy way for us to be good as a family.”

Saying he’s “been through a sh*t-ton of stuff,” Jonas concludes, “Now that I’m 24 and have control of my life, I’m going back to the drawing board.”
