She recently revealed that she is now the co-owner of CAST, the treatment center where she received help for her depression, eating disorder and substance abuse.

Lovato checked herself into the L.A. based facility in 2013, but this may actually be her first time admitting to this rehab stint. She's been public about her decision to go to rehab following her altercation with a backup dancer in 2010, but she'd previously told Fitness magazine that she "almost went back to rehab" in 2013 for her eating disorder. Either way, we're just glad she received the help she needed.

In an interview with CBS News published Thursday (September 8), she confessed that while she had been a "nightmare" patient during her stay, her time at CAST "changed [her] life" — and now she wants to pay it forward by helping others.

In fact, she believes in CAST so much that a team from the center, including founder Mike Bayer (Lovato's "rehab guru," pictured above with her and the Obamas), have joined Lovato and Nick Jonas on their "Future Now" tour, offering workshops to promote mental health awareness.  

Her reason for becoming co-owner of CAST is simple: "It just feels good," she told CBS' Tracy Smith.

Beyond her role as a pop superstar, Lovato hopes her legacy is one of service. 

“It sounds ridiculous but, like, I kind of made a pact with God,” Lovato told Smith. “And I don’t even think you’re supposed to do that, but I was, like, I promised, ‘If you make me a singer one day, I’m going to use my voice for so much more than singing, and I’m going to help people with it.’” 

Fans celebrated the news by acknowledging all that she continues to accomplish.

And many applauded her for being the awesome advocate she is.

Lovato seems to be living out her mission as intended.

As noted in our story about how Lovatics are inspired by the singer's candidness about her struggles, many find strength from her music when dealing with their own personal issues. One fan told us, 

I became depressed and began self-harming (and continued for almost a year). God, my family and Demi got me through that very dark period of my life. Her song 'Warrior' speaks to me in so many ways and I feel stronger every time I listen to it.
By choosing to become co-owner of her former treatment facility, Lovato has taken another huge step in advocating for people to seek help no matter how trying their circumstances.
