Later, Jonas reveals that the "Neon Lights" singer and fellow Disney Channel star Miley Cyrus, 21, forced him to smoke pot when he was just a teenager.
Despite the unfavorable report, Lovato has nothing but “love” for her former flame.
“@JoeJonas love you brother. #family/#friendsforever,” Lovato tweeted–a remark that shocked many fans.
Her sister, however, isn’t happy about Jonas's tell-all. Dallas Lovato took to her own Twitter account to spurn the former Jonas Brother: “Pathetic how people cut others down to get attention off themselves. Loser,” she wrote.
