This will MOST definitely go down in history as one of the most memorable opening performances at the MTV VMAs.
Lady GaGa showed up as her alter ego Jo Calderone and started off the 2011 VMAs with one amazing bang!!
Performing You and I, GaGa/Jo had the performance of the year! Queen's guitarist Brian May also joined her on stage!! AH-MAZING!!! (Dave Grohl's reaction at 06:31 is priceless!)
You have to see it for yourself. Watch the performance above!!
