Demi Lovato Preforms 'Skyscraper' on America's Got Talent, 'AH-MAZING'

Demi Lovato @ddlovato killed it again with SkyScraper on AGT. That was amazing, a fan wrote on Twitter. Demi Lovato performed on America's Got Talent Aug. 24 on NBC. Many agree her performance was truly breath-taking. AH-MAZING, another fan tweeted.

The 19 year-old star sung her latest hit, Skyscraper. Lovato spent most of last year out of the limelight because personal issues. The Disney singer was reported to have been battling with her recent break-up with singer Joe Jonas, pressure from the media, and an eating disorder she had been struggling with for approximately six years. When Lovato allegedly punched a backup singer from her Camp Rock 2: The Final Jam tour, friends and family knew it was time to get the singer help. She spent some time in rehab to work on those issues privately.

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

Her performance on American's Got Talent, was more than just singing, it was a full on show. The singer begins seated on furniture and bedroom items that have been clustered and mounted to form a mountain of some sort. The stage is dark, but it soon becomes enlivened as Lovato makes her way out of the rubbish. She struts to a piano for a few minutes and finally graces center stage for a dramatic finish amongst wind machines and bright lights.

Beyond the words of Skyscraper, 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 where Lovato had performed Skyscraper for the first time. 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.

Overall, the album is said to be fun and very impressive. 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.

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.

You can catch Demi Lovato's performance on the Do Something Awards Thursday on VH1. Her album will be released on Sept. 20.
