Katy Perry’s reactions were the best part of the 2015 Grammys

One of the best parts of any awards show is when the camera cuts into the audience without warning, catching celebrities in a moment of candor. When is comes to entertainment, pre-prepared speeches can't compete with an off-brand facial expression or just the star enjoying themselves like a normal person.

Katy Perry was the stand-out goofball of the night for the 2015 Grammys. From the red carpet onward, she was a treasure trove of fantastic reactions.
