Demi Lovato has been named one of Maxim magazine’s Hot 100 … but she sees beauty in what she has on the inside.

“To me, sexiness stems from being confident and comfortable in your own skin,” the “Neon Lights” singer — who came in at No. 40 on the list — told the magazine, adding that her best feature is her “butt.”

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

Demi, 21, also shed some light on what it takes for a guy to catch her eye.

“To get my attention a guy must be genuine, supportive, real and have the ability to make me laugh,” explained the singer, who has been seeing Wilmer Valderrama on and off since 2010.
