Demi Lovato is showing off her sexy curves in a stunning bright yellow Yigal Azrouel dress on the cover of Cosmopolitan. She definitely has the X Factor!

The 19-year-old "Skyscraper" singer, who was hospitalized late last year due a reported eating disorder, opens up about being diagnosed with bipolar disorder. Demi says:

    "I felt relieved when I found out. Like I’m not completely crazy; there’s a medical reason for all of it. 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.”

So what's on tap for the X Factor judge? She adds, "I want to be married with kids in 10 years.”
