After spending November 2010 - January 2011 in a treatment facility for bulimia, anorexia, self-mutilation by cutting, depression and bipolar disorder, Demi Lovato is standing tall with hit comeback single 'Skyscraper.' The towering song has garnered praise from stars like Katy Perry, Kelly Clarkson and Pete Wentz and has already been covered by Jordin Sparks.

As she puts the finishing touches on her third studio album -- the first since her stint in rehab -- Demi reveals to AOL Music that she does not consider herself to be recovered and even considered quitting showbiz altogether. The 18-year-old admits she looks to actor Robert Downey Jr. as an "inspiration," and hopes to motivate others to get healthy. And, of course, Demi addresses those Ryan Phillippe dating rumors.

Get the details on all this and more in our exclusive interview with Demi below, and tune into Cambio's Live Chat with Ms. Lovato herself on Thursday July 21 at 8PM EST/5PM PST.

You've been getting rave reviews from other artists for your new single 'Skyscraper.' What's your reaction to all of the praise and support?

There has been so much positive feedback, it's been so incredible. I hear that people like Katy Perry and Kelly Clarkson respect my music and are even tweeting about it on their own time. I mean, it's just been so amazing and I've been so thankful and grateful. It's just so exciting for me, because these are people I look up to myself and then hearing that they're tweeting about me; it's like a dream come true.

Do you think any collaborations might come out of all this?

I would love to collaborate with these people. I haven't had the opportunity yet, but maybe in the future. That's something that will definitely be on my wish list.

Who have you been working with on your new album?

I've been working with [producer and songwriter] Toby Gad and with a couple named Dan [Pringle] and Leah [Haywood], they're with Dreamlab Productions. They're amazing -- we've done some really great stuff together. I worked with Ryan Tedder the other day, from OneRepublic. And Tim [James] and Antonina [Armato] from Rock Mafia. So I've worked with some really incredible people and I'm really excited for the other people that I'm going to get to work with soon.

People are calling 'Skyscraper' your comeback single, and it has a very inspiring and powerful tone and message -- will the rest of the album follow this strong, self-empowerment theme?

The sound and feel of the album is going to be a lot lighter. With 'Skyscraper,' we wanted to come out of the gate with something very inspirational and something that represents the journey that I've been on. But the rest of the album is a lot lighter and more fun.

It's definitely a lot more mature than the other stuff that I've done. It's not pop rock, it's more R&B vocals and it really showcases my vocals, which I'm really proud of. There are some other songs that are as equally intense as 'Skyscraper' that I'm excited for people to hear, but for the most part it's going to be a lot more fun.
