Demi Lovato is done with being serious -- it's now time to introduce her "badass" side.

And she kickstarted it with her brand-new seductive, sexy single, "Cool For The Summer."

"I'm no longer serious. I'm done with the sob stories and the tales," Demi told Ryan Seacrest. "New chapter, new life, new album, new single, this is a completely new Demi."

Don't get her wrong, she's still proud to be a strong role model for her Lovatics, but there is a side of her that she's been hiding for quite a while, and now is the perfect time to reveal it.

"It's been so long just focusing on kind of people-pleasing, making everybody happy with being the best role model that I could be, and I think at the end of the day I am outspoken about the things I believe in -- about mental health, advocacy work, I have my own charity, all these things that make me a role model," she said. "But at the same time none of these things are representing the badass that I am."

With lyrics on "Cool For The Summer" that are sexier than ever -- "Got a taste for the cherry/ I just need to take a bite"-- Demi is gearing up to release more "provocative songs" on her album, which is due this fall, and to incorporate several different genres of music.

"There's also an element that I really wanted to bring to the music -- one was the rock element, I wanted to bring that rock/pop music, but I have a lot of rhythmic flares in there as well," she said. "There's so many things I wanted to bring back. I grew up listening to soul music and then I only listened to metal music for a while, so I have so many influences."

And she's hoping with this new attitude and sound people will start gaining a different perspective on who she is, much like Rihanna and Nicki Minaj.

"There's nobody in the pop industry that says don't f--k with me," she said. "There's Rihanna and Nicki Minaj, those two women, they're like, 'I'll kick your ass.' And that's the thing I'm totally that -- but in pop music... it's kind of a different world."

She added, “There’s a side of [me] that people don’t get to see with my past music, but it’s been there. It’s totally been there. And like, hey, just because I’m sober doesn’t mean that I’m judging anybody else for their stuff. And also, it also doesn’t mean I didn’t have a damn good time back then either. I’m having a good time sober -- a better time for sure.”
