Demi Lovato brought the house down during the America’s Got Talent semi-finals result show Wednesday evening. The singer, who completed a stint in rehab earlier this year, sang her new hit single “Skyscraper” as the crowd roared with applause and cheers.

Giving a powerhouse performance, the 19-year-old appears to be back — and better than ever! On stage, she wore a long black dress, cropped jacket and tons of jewelery. Watch the video above to see her performance.

Of course, this isn’t her first comeback performance. Earlier this month, she performed at the Do Something Awards. Demi admits she wouldn’t be where she is today, if it weren’t for her loyal fans.

The former Disney star chatted with Ryan Seacrest on his KIIS FM morning show, saying:

“These shows are basically thanking my fans for being so supportive throughout this entire journey. … This is the first time that I will be on stage in about a year.”

Demi announced that she’s going back on tour — first starting with two dates at The Hammerstein Ballroom on 9/17 and at Club Nokia on 9/23.  Her highly-anticipated album will be released on Sept. 20 and feature collaborations with Missy Elliott, Timbaland and breakout star Jason Derulo.
