From Disney princess to Maxim hottie! Demi Lovato made it to no. 40 on the Maxim Hot 100 issue, which will be out on June 3. Prior to the issue's release, Us Weekly got a sneak peek of the singer's interview for the coveted spot on the list.

"To me, sexiness stems from being confident and comfortable in your own skin," the "Neon Lights" singer, 21, explained. She thinks her best physical attribute is her "butt," but when it comes to her personality, she had a more thoughtful answer. 

"The ability to work at bettering myself—I'm not perfect, no one is, but I'm working at becoming better everyday," she continued. "Everyday I can look back and say I'm in a better place than I was yesterday."

Lovato has been dating That '70s Show star Wilmer Valderrama since 2010, and has a clear idea of what she wants in a man.

"To get my attention a guy must be genuine, supportive, real and have the ability to make me laugh," the former X-Factor judge dished.
