On Dec. 2, 2013, Demi Lovato tweeted an amicable response to her ex-boyfriend Joe Jonas after his confessional essay "Joe Jonas: My Life as a Jonas Brother" was published by New York magazine on Dec. 1.
Lovato tweeted: "@joejonas love you brother. #family/friendsforever."
In the article, Jonas (who briefly dated Lovato in 2010) had this to say about his drug use: "The first time I smoked weed was with Demi [Lovato] 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. I don't even smoke weed that often anymore."
And Jonas (who is 24) offered this perspective of his relationship with Lovato: "We eventually dated for a month. 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."
Lovato (who is 21) has been very open with the public about her personal battles with substance abuse, self-harming and eating disorders. She has spent time in rehab for these issues. Lovato has also gone public about being bipolar.
She rose to fame as a Disney Channel star in the "Camp Rock" movies (co-starring the Jonas Brothers) and on the sitcom "Sonny With a Chance." Lovato has also had a successful career as a singer. All four of her albums have debuted in the Top 10 in the U.S. and have been hits in other countries.
Lovato became a judge on "The X Factor" U.S. in 2012. She has remained friendly with the Jonas Brothers (Joe, Kevin and Nick) since her breakup with Joe. In 2012, Lovato recruited Nick Jonas to be a guest mentor on "The X Factor" during the "judges' houses" phase of the competition to help her choose contestants who would go on to perform in the live episodes.
In 2012, Joe Jonas was a talent-show judge on the CW network's critically panned "The Next," which was cancelled after one season due to low ratings.
In 2013, the Jonas Brothers cancelled their U.S. tour and announced that they have disbanded and are pursuing their solo careers. Tabloids have hinted that Joe Jonas as a drug problem (there are rumors that he's a heroin addict), and there was speculation that he was in outpatient rehab when he was seen with Lovato's sober coach, but Joe Jonas has denied the rumors.
