LOL, she does NOT live in LA. She for one, has said that she hates LA, because it isn't for her; she was born and raised in New York, and when she is not touring she lives there. She live in Manhattan. That is where my knowledge lies. Hope i helped in bringing correct, and useful information -_-
Okay, first of all, she lived in LA for awhile, and then she moved back to NYC because she couldn't stand LA. She still lives there to this day, but is hardly home. Somewhere in Manhattan. (This is actually what the song Marry the Night is about..)
