Katy Perry was nothing but perfection at the LA premiere of her movie "Katy Perry: Part Of Me".
Katy looked like a classic Hollywood movie star when she walked the red carpet in a beautiful red velvet vintage style dress with a cake purse. Oh and her grandma rocks a glittering walking stick!
Katy Perry then performed for the crowd and she had something a little more special planned for her performance. Katy burst out of of a popcorn carton dressed in a film reel top, puffy popcorn skirt and glasses with candy on them.
Watch Katy perform Wide Awake at the premiere HERE.
