Many young stars have battled addiction under the spotlight, through no choice of their own—but 19-year-old pop singer Demi Lovato has been one of the youngest celebrities to speak openly about the challenges and triumphs of recovery. “It’s a daily thing; you don’t get time off from it,” Lovato says in an interview for the July issue of Cosmopolitan. The former Disney star—who's also the newest judge on the hugely popular TV talent show The X Factor—spent some time in rehab in 2010 to treat various "physical and emotional issues," including bulimia and cutting. Lovato has also endorsed the sober lifestyle; "'Sober is Sexy' is my new motto" she told Seventeen earlier this year. But while her career seems to be on the upswing, the singer and actress admits that being in recovery isn't always easy, and that she can't do it by herself: “If I feel myself slipping back into old patterns, I have to ask others for help, which is hard for me to learn, because I really like doing everything on my own.”
