Demi Lovato is opening up. Ahead of the release of her new album Confident, the "Cool for the Summer" singer is popping up on the October/November over of Complex magazine, and she is not holding back. The 23-year-old pop star talked about everything form her relationships with Selena Gomez, Justin Bieber, Iggy Azalea and Wilmer Valderrama, her sexy image and her desire for a Grammy.

Lovato may be a bit of a private person but she was very open about talking about some of her famous associates. Though she and Gomez took a selfie teasing the release of her old friend's new song "Same Old Love," she said that they don't talk much, simply saying "Nope," when asked if they talk anymore. However, it had nothing to do with Bieber.

"He's actually a nice guy. I don't really know him that well, but he seems to have grown up. He looks like he's maturing," she said about Bieber. But when it comes to Gomez, she implies they just grew apart. "But, you know, when you're young and you get older, you change and people change. You have things in common, and then all of a sudden, you don't. It's just a part of life."

Though Lovato seemed to imply that most of her friends are not famous, she talked up her longtime boyfriend, saying that he's "very family" and praised Iggy Azalea.

"She's very, very, very real. What you see is what you get. I think sometimes that pushes people away, but that's what I admire about her. She's the furthest thing from fake," she said. "In this entertainment business, that's so hard to find with anybody. That's why I don't have any very famous friends. The very few that I do have are real."

Lovato wasn't there just to dish on other celebrities, she was also there to talk about her new music. Noting that she now has the confidence to be sexy and sing about things that she hadn't touched on before, Lovato insisted that she's aiming high - for a Grammy.

"I want the Grammy committee to hear ["Stone Cold"] so that one day they can see that-I know that I'm capable of getting there. I just want people to see it finally. When I say getting there, I don't mean winning one. I just want to be nominated for one. You can't go higher than the Grammys in the music industry," she said. "That was a huge goal for this album. I watched the Grammy nominations last year and I was like, "I want to be there so bad." It really gave me that kick in the ass to make music that was worthy of it. This is a song that I feel like is worthy of notification."

But, time will tell. Lovato's new album Confident will be released on Oct. 16.
