The scoop on Demi Lovato and Miley Cyrus fallout

Demi Lovato is doing what's best for her well-being, and sometimes that includes distancing yourself from certain people.

The 22-year-old pop star revealed during a radio interview this morning that she and fellow Disney darling Miley Cyrus are no longer friends, and now, E! News has the details behind what exactly happened between the former gal-pals.

An insider tells us that, "Miley is a wild card and Demi has made a point of not surrounding herself with people" who party too much, adding that "Demi's sobriety is very important to her."

"Demi tries to be reserved in public and cares very much about how she is perceived," the source continues, and mentions a recent encounter between the duo.

"About six months ago at a small gathering, both Miley and Demi were there. They were in the same room for only a few moments, and it was super-awkward, very girly high-school, pretending to ignore each other. They didn't speak, they didn't even make eye contact."

The status of their relationship was brought to question when a fan asked Lovato to describe her current connection with Cyrus on The TJ Show Boston's 103.3 AMP Radio today.

"Um…yeah…that, um…we're, we're like...we're acquaintances," Demi said. "It's life, and people change." She added, "I don't have anything in common with her any more. I wish her the best."

Although these two won't be spotted hanging out together any time soon, Lovato still had nice things to say about the Bangerz singer.

"Miley has been one of my best friends growing up and so I'm happy for her," the "Heart Attack" singer raved on Fox 31's Everyday in October 2013. "She's doing what she wants to do and this is her time to break out and figure out, you know, what she wants to do in her career and her image and everything...I'm happy seeing her happy because I love her so much. And, you know, she doesn't care what people think, nor should she."
