Demi Lovato may not by vying for the coveted mirror ball trophy but she definitely brought down the house when she performed on Dancing with the Stars stage Tuesday night. 

The Unbroken singer sang her hit single “Skyscraper” that is sure to give you chills! Dressed in a flowing gown and a loose braid, Demi sang as dancers performed around her.

The former Disney star may be a good luck charm for her friend Rob Kardashian. 

Demi has been showing support for the DWTS contestant via Twitter. When voting began for the Dancing stars on Monday night, she wrote:

 “Everyone vote for my very good friend @RobKardashian tonight on Dancing With the Stars!!!! #VOTE4ROB

Rob isn’t the only one who has something to celebrate as he was spared Tuesday night on DWTS. Demi tweeted Wednesday morning: 

“Skyscraper went gold!!!! Ah!!! Thank you all so so so much!!!!”
