Since Demi Lovato's comeback to the Hollywood scene, fans and fellow celebrities have been nothing short of impressed at her maturity, composure, and honesty when speaking of her past issues.

Amazing when people put themselves into their art completely, Pete Wentz said. The new song Skyscraper by @ddlovato is pure perfection, Katy Perry tweeted. Her voice is one of the BEST undiscovered beauties. Can't wait for the full record. Kelly Clarkson wrote that she purchased the song on iTunes, called it cool and her voice rad.

Demi Lovato is one of the reasons I smile everyday. Thank you for keeping me smile and stay strong,a fan wrote on Twitter. Demi Lovato was always my role model, and she always will be.♥ another fan expressed.

Demi Lovato's single Skyscraper has been an encouragement to all people. BFF, Selena Gomez, even tweeted: SO, SO proud of Demi Lovato, Skyscraper. Incredible, beautiful and so inspiring. The empowering ballad is truly moving.

Beyond the words you can sense a transparent, vulnerable, and fragile Lovato expressing her heart especially during the chorus-- You can take everything I have/ You can break everything I am/ Like I'm made of glass, like I'm made of paper/ Go on and try and tear me down/ I will be rising from the ground like a skyscraper.

This song is so special to me because it's inspired by my journey and the struggles that I've dealt with this past year, Lovato said in a recent interview with seventeen.com. I hope people are able to relate to it and realize that they are able to rise above and overcome any obstacle, no matter the circumstances, and shine like a skyscraper.

Ryan Tedder of OneRepublic who collaborated on a track with Lovato claimed that her comeback album, Unbroken, will shock everybody.

Demi blew me out of the water vocally! He said at the Do Something awards. I had no idea how good her voice is. She's one of the best singers I've ever worked with. Literally, that good...I mean, she's a Kelly Clarkson-level vocalist. And Kelly has a set of pipes.

Tedder explains that the track he co-wrote and produced for Demi -- Who's That Boy? is different from Skyscraper. I think everybody wanted to hear her talk about that, and this is basically flipping it 180, saying, 'Oh, by the way, I'm still also just young and want to have fun.' There's even like a little rap feature on it ... She's got a couple features on this album, one in particular that is going to shock everybody. I was like, 'How did you get this person? They're impossible to get and you got them!' Tedder added.

Demi has remained hush-hush about which stars, exactly, will be making an appearance on her album. Rumors surfaced that her BFF's boyfriend, Justin Bieber, would be the singing a duet on Unbroken. I don't know where the Justin Bieber rumor got started, but that one is not true, Demi told Latina.com

However, on On Air with Ryan Seacrest, the young star announced who the features would include. Lovato is letting her Hip Hop flow with DEV, a female rapper who is the Tedder-produced track--
Who's That Boy? Iyaz is the artist who will be singing a duet in You're My Only Shorty.

One of the best experiences I've had was definitely flying down to Miami to go work with Timbaland and Missy Elliot. Missy Elliot got on one of the tracks, and it's called 'All Night Long.' It was really fun! Demi exclaimed as she described one of her favorite moments in the studio.

Overall, the album, Unbroken, is said to be very impressive. Many are expecting this album to be a big one for Demi Lovato.

Fans are very excited that Lovato has a bright outlook on life and is not allowing anything to hold her down. Her comeback is on to a great start!

I am still on a personal journey dealing with my own issues each and every day, but the best advice I can give to anyone going through a rough patch is to never be afraid to ask for help.

Demi Lovato's album--Unbroken-- will be released on Sept. 20.
