Okay Lovatics, you might want to sit down before listening this... because this video might knock you off your feet.
With Kurt both at the piano and playing guitar, the duo took favorites like the emotional ballad "Skyscraper" and newer hits like "Heart Attack," incorporating them into one fluid song. It might even give this T-Swift medley a run for its money. Watch in the video above.
Lovatics, what do you think of Kurt and Sara's medley? Sound off in the comments or tweet @HuffPostTeen!
