With two backup dancers, the comeback queen known as Demi Lovato performed 'Who's That Boy' and her ballad 'Skyscraper' on 'Good Morning America.'

Demi was back in fine, fine form, with flawless dance moves and that pretty voice. Decked out in a floral dress and studded black leather jacket, which illustrated both the soft and edgy sides of the singer (complemented by her wild mane of wavy, brown-highlighted hair), Demi rocked her body! She gave one of the most sensual performances of her young career, all on a breakfast TV show.

This footage (below) is from the sound stage; it's not the televised clip. It's also only of 'Who's That Boy,' a much fluffier, dancefloor-ready follow up to the heavy, emotionally resonant 'Skyscraper,' which was autobiographical for her, given her public struggles and her recent treatment.

Clearly, going away and seeking help was the best thing Lovato ever did. She is performing like a woman possessed. That, coupled with the fact that she wants to be a role model for young girls struggling with similar issues, make 2011 the year of Demi.

Lovato's brand new album, 'Unbroken,' is out today, Sept. 20.
