Demi Lovato brought the house down with her tender rendition of "Skyscraper" at Sunday's Do Something Awards, which aired Thursday on VH1.

It was the first time the 18-year-old singer performed in front of a live audience since checking into rehab last October.

"Thank you so much for all your sweet comments on my Do Something Awards performance!" a proud Lovato told her 4 million Twitter followers Thursday. "Love you all!"

Lovato's third studio album, Unbroken, is out September 20.
