The ‘X Factor’ judge unleashed her hot new single on the ABC reality series. Watch her incredible performance here!

Wynonna Judd may not have had the best night on Dancing With The Stars — the country singer was eliminated on the April 2 episode — but Demi Lovato, 20, had the time of her life! The pop-rocker, who recently revealed sexy art for her new album Demi, performed “Heart Attack” live; and even with a hint of a cold, she sounded amazing!

“So excited to sing ‘Heart Attack’ on Dancing with the Stars!!” Demi tweeted shortly before taking the stage.

And not only did Demi sound amazing belting out her vocally challenging single, but she also looked incredible! Ever since joining The X Factor, Demi’s been sporting some over-the-top styles — her pink and blonde hair comes to mind — but now she’s clearly getting back to her rocker roots.
