Jennifer Lawrence has been pure class and beauty during her whirlwind press tour for Mother! this month, but her true and raunchy self (which we like better, tbh) came out when she stopped by Late Night With Seth Meyers on Thursday. The actress, who made her red carpet debut with boyfriend Darren Aronofsky this week, told Seth an epic story about a crazy bar fight she got into during a night out in Budapest, Hungary.
