Sure nobody was expecting this very mature reaction. Singer and "X Factor" judge Demi Lovato's responded to Joe Jonas's drug comments and she wanted to make sure everyone knew she was cool with it."@joejonas love you brother #family/friends forever," the 21-year-old wrote on her Twitter page.

Lovato's older sister, Dallas Lovato, was not so happy with Joe's comments. "Pathetic how people cut others down to get attention off themselves...Loser," she tweeted.

On the December 9 issue of New York Magazine, Jonas wrote a very revealing essay, where he spilled about his relationship with the "Heart Attack" singer. The 24-year-old star claimed they only dated for about a month.

"I really got to know her," wrote Jonas, "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 continued, "Demi ended up punching a girl in the face on a place, 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 to rehab.'"

The former Jonas Brothers singer also wrote the first time her ever smoked pot. "The first time I smoked weed was with Demi and Miley [Cyrus]," he says. "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."

"Now that I'm 24 and have control of my life," wrote Jonas.  "I'm going back to the drawing board."

Lovato has moved on and nowadays she is keen on sharing details from her troubled past, so others can learn from her experience. Now, she wants to release a memoir about her struggles with drug addiction and her time in rehab.

"I'm battling with internal thoughts on how honest I should be," said the former Disney star. "Yes, I've been very honest, but if people really knew how dark and deep my struggles got -- not just with my eating disorder but with drugs and alcohol -- they'd be really shocked. But I'll most likely end up saying everything. Maybe it'll help other people in the industry who are headed down the wrong path," she said, according to the Huffington Post.
