Joe Jonas allegedly corrupted by weed loving Hannah Montana

Joe Jonas was introduced to pot by Demi Lovato and Miley Cyrus, he has claimed.

Jonas revealed his hard partying ways on Vulture.com, where the singer shared he lost his virginity at 20 and smoked weed with Hannah Montana.

The 24-year-old singer admits that although he and his brothers Kevin, now 26, and Nick, now 21, wore purity rings to represent their "promises to ourselves and to God that we'll stay pure till marriage," they took them off years ago.

"I lost my virginity when I was 20. I did other stuff before then, but I was sexually active at 20," Jonas explains in his Vulture post. "I’m glad I waited for the right person, because you look back and you go, ‘That girl was batshit crazy. I’m glad I didn’t go there.’”

“When I was 20, I started dating Ashley Greene, and she was my first serious relationship. We were together for almost a year," he explains. "I was living out in L.A. by myself, and at the end of the day, long distance didn’t work. It’s incredibly difficult. I did a cover story with Details acknowledging the relationship, and the day after it was on newsstands, we announced our breakup. That was just coincidence, but it’s funny how that always happens, right?" "After Ashley, I took two or three years to just be single," he adds. "I was hooking up and having fun. Now I’m with someone I really care about. We get each other.” http://www.vulture.com/2013/11/joe-jonas-talks-jonas-brothers.html Jonas is currently dating Blanda Eggenschwiler.

Jonas also reveals former girlfriend Demi Lovato and Miley Cyrus got him to try pot for the first time.

“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," he says. "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.”
