Jennifer Lawrence wasn't the only funny woman in the room when she attended Elle magazine's Women in Hollywood celebration in Beverly Hills, CA, on Monday. The actress was at the event to introduce her Hunger Games costar Elizabeth Banks, who was honored with an award during the festivities. While at the bash, Jennifer made sure to mingle with Amy Poehler, who was there to honor her longtime pal Tina Fey, who costarred with Elizabeth in 30 Rock. Other guests included Jennifer Garner, who caught a case of the giggles from Tina while posing for photos; Kerry Washington; Renée Zellweger; and Lizzy Caplan. Jennifer and Elizabeth will get even more time to bond in the coming weeks as they gear up to promote The Hunger Games: Mockingjay — Part 1, which hits theaters in November.
