Demi Lovato released a racy video for her upbeat dance single Neon Lights.

The video features the 21-year-old dancing in a club while wearing bright makeup and also swimming around in a body of water naked.

In another scene, the X Factor judge also shows off her flexibility as she arches her back while laying on the floor with rain pouring down on her. 

Did Demi Lovato Diss Carrie Underwood On X Factor?

The song is the third single off Lovato's fourth studio album, Demi, which was released in May. In February, the singer will head out on the Neon Lights tour to promote the album, along with former X Factor contestants Fifth Harmony as her opening act.

"I think it's going to be so much fun," Lovato told Ryan Seacrest in September. "There's nothing better than woman empowerment and having an all-girl tour. What's ironic is we are all from The X Factor, and that wasn't even planned. It just kind of happened that way. I helped put Fifth Harmony together and watching them now, they're going to be opening for me, it's so awesome."

As her career is heating up, the singer also sat down with Good Morning America and spoke about her new book, "Staying Strong," in stores now. The book encourages her fans to stay positive no matter what situation they are facing.

"A lot of times my fans asked me, 'You know you helped me get into recovery, or because of you, I went into treatment. You saved my life,'" Lovato said earlier in November. "They're incredibly sweet things that I'm very, very grateful for, but the question that a lot of people have for me is 'How do you continue to stay strong?'"
