AND THEN THERE WAS GAGA!

GaGa was in another world during the Grammy's, IN AN EGG!

She only went out when it was time for her to perform "BORN THIS WAY"

GaGa was wearing Mugler in all 3 pics above. And yes, she has "horns" and "exaggerated shoulders" as part of her body makeup. She is really dedicated as even in interviews and candids, she was wearing this. So obvious this has something to do with Born This Way.

And it's obvious she would be wearing Mugler as promotion as Nicola Formichetti, her stylist is creative director of the house.
