In his most revealing interview yet with Vulture magazine, Joe Jonas of the recently split Jonas Brothers band opened up about his first time smoking weed, losing his virginity and life as a JoBo.

Jonas released a memoir-like expose on his life pre and post-fame, from his beginnings as a pastor's kid and active membership in the church to his love affair his music at an early age.

"I believe in God, and that's a personal relationship that I have, but I'm not religious in any way," the 24-year-old singer admitted.

When Disney channel came into the picture, the lives of Joe and his brothers Nick and Kevin changed dramatically. The young teens were propelled to stardom after years of struggling to make it in the music business, playing "any venue" that would have them. After Disney, their "fan base exploded," as their sound and style perfectly fit in with a younger market.

"Being a part of a company like that comes with certain expectations. Not overtly, but there was a subtle vibe. We were working with Disney in 2007 when the Vanessa Hudgens nude-photo scandal happened. We heard that she had to be in the Disney offices for a whole day because they were trying to figure out how to keep her on lockdown. We'd hear execs talking about it, and they would tell us that they were so proud of us for not making the same mistakes, which made us feel like we couldn't ever mess up. We didn't want to disappoint anyone-our parents, our fans, our employers-so we put incredible pressure on ourselves, the kind of pressure that no teenager should be under," Joe revealed.

Jonas also opened up about his short-lived relationship with "Camp Rock" co-star Demi Lovato, and how he felt like he needed to take care of her as she went through her own private struggles with drugs and an eating disorder.

"It was an insane situation to be in. Things kept building up, and 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," he said.

While the Disney machine came with its own restrictions, ironically, the first time Jonas tried marijuana was with Miley Cyrus and Lovato.

"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," he admitted.

Recently Demi Lovato has started to open up more herself about her dark struggles with drugs and alcohol. While the 21-year-old singer and "X-Factor" judge has been exceedingly honest about her issues with self-harm and mental illness, she plans to write her own tell-all in the form of a forthcoming memoir as part of her multiple-book deal with Macmillan Publishers, which she is admittedly "nervous" to write.
