Despite their G-rated image and their purported "chastity pledges," Joe Jonas is now revealing that his time with The Jonas Brothers involved lots of sex, drugs, & rock'n'roll, including a weed romp with fellow Disney stars Demi Lovato and Miley Cyrus.

According to the New York Daily News, Jonas has revealed that he first tried pot when he was "17 or 18" years old, and it was Lovato and Cyrus who encouraged him to try it. "The first time I smoked weed was with Demi (Lovato) and Miley (Cyrus)," he said. "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. 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."

But that's not all the now-all-grown-up pop star revealed. According to Newsday, even though he & his brothers were purported to be all about "chastity pledges" and good clean living, they were anything but sweet little angels. In fact, the middle Jonas brother lost his virginity at the age of 20. "Back then, we explained that we had made these promises to ourselves when we were younger. A few months later, it comes out that we're in some cult and that we're these little staged Mickey Mouse kids. People were coming up to us, saying, "Thank you so much, I'm waiting because you guys are, too!" And we just thought, No! That's not what we're about," he said.
