Demi Lovato's Music Reflects Her 'Open Heart'

'It's nice being able to tell the truth,' Lovato says of Unbroken and her 'Stay Strong' documentary, which debuts tonight at 10 p.m. on MTV.

Demi Lovato is no stranger to being honest about her ups and downs. When she dropped Unbroken last fall, several of the cuts, including the album's staggering lead single, "Skyscraper," seemed to reflect on her own personal journey.

Recorded after she left a treatment center in 2011, the album was full of not only girl-power anthems, but also reflective ballads about the struggles of loving both yourself and others.

"The album I wanted to keep upbeat and uplifting; I didn't want to come out with this depressing album. I think it's important that I kept a lot of my heart open on the album because I talked about my personal issues," she told MTV News about the release before tonight's premiere of her MTV documentary, "Stay Strong," which also touches on many of her personal issues and trying her best to put her life back together after entering rehab in October 2010. "But I also had some fun dance songs on there for people to enjoy," she added about the album.

Whereas some pop stars tend to shy away from their own lives on their albums, Lovato fully embraced the joys and the sorrows of her life. "I think it's nice being able to tell the truth and being able to really talk about these issues rather than hiding it and not talking about it and sharing it," she added. "So I think I enjoy it more than anything I'd done before when I was trying to hide everything." The album's next single is "Give Your Heart a Break."

Lovato is set to welcome fans into her life when "Stay Strong" debuts tonight at 10 p.m. ET/PT on MTV followed by a live Q&A with the star during "The After Show" at 11 p.m. ET/PT.

"I've just been working at it a day at a time and have been trying to continue to fight my hardest," she told us about still dealing with her problems in the public eye. "And I've had my ups and downs, and I'm still trying, but overall it's been a really great journey, and I'm thankful for everything that I've been through."

Don't miss "Demi Lovato: Stay Strong," debuting tonight at 10 p.m. ET/PT on MTV.
