Demi Lovato Duets Skyscraper With Fellow Glee Co-Star Darren Criss!

Prepare NOT to give your heart a break watching this, and ready the tissues because you will need all of them.

Demi Lovato and Darren Criss teamed up outside of Glee for Demi’s concert at Toronto’s We Day festival, to perform her hit Skyscraper.

Not only did Darren sing some sweet vocals with Demi, he also tickled the ivories, and what’s that beautiful heavenly harmony? Oh, that’s right, that’s the Kenyan fuh-reaking Boys Choir!

We will be rising from the ground…to give Demi and Criss a huge standing ovation for this collaboration! Bellisimo!

Ch-ch-check out the AHmazing duet (ABOVE) and prepare to shovel and pail your heart after it’s melted to the floor.
