Demi Lovato knows exactly what she wants in a man.
"I don't have many deal breakers. I've done so much in my life, it doesn't feel right to judge other people," the 19-year-old tells the July issue of Cosmopolitan. "Oh, I know one quality I won't tolerate: I would never be with a guy who is controlling."
Though she's currently single, Lovato, whose exes include Wilmer Valderrama and Joe Jonas, envisions herself walking down the aisle and starting a family by the time she turns 29. "I want to be married with kids in 10 years," she tells the magazine.
The teen superstar, who will join Britney Spears, 30, on "The X Factor" this fall, also opens up to Cosmopolitan about being diagnosed with bipolar disorder while seeking treatment at Timberline Knolls in late 2010.
"I felt relieved when I found out. Like I'm not completely crazy; there's a medical reason for all of it," she explains. "It's a daily thing; you don't get time off from it. And 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."
In addition to filming "The X Factor," Lovato will kick off her summer tour June 12 in Del Mar, Calif.
