Forget about the 'Gangnam Style' dude, this grandma has it going on! Her dancing is incredible, and based on the related videos, these aren't the only sick moves she has.

Grandma Dances To Usher

This grandmother really seems like she should be cooking, or baking sweets for her grandchild, but instead - she is far more interested in making YouTube magic for all of the world to see. If I didn't know any better, I'd think that Usher gave her private lessons.

Not bad Granny. Not bad at all.
