She didn't disappoint! Demi tweeted out her thanks to concert-goers on Sunday, writing, "Orlando, you were amazing."
Demi also sang "Heart Attack" at Rodeo Houston, so the new single is definitely getting a workout for concert audiences.
She also performed "Skyscraper," telling the crowd before-hand, "I perform on stage with a purpose and that purpose is to reach out to somebody that struggled with the same issues that I've struggled with...I'm living proof today that you can get through it...you can make it out alive. You deserve happiness and life is worth it."
