Jennifer Aniston looked hot in white Burberry last night at the AFI gala honoring Shirley MacLaine in LA. The event gave Jen a chance to catch up with many of her actress pals, including Meryl Streep, Julia Roberts, Melanie Griffith, and Sally Field. Jen even said hi to her Horrible Bosses leading man Charlie Day and his wife, Mary Elizabeth Ellis. The bash honored the life and work of Jen's Rumor Has It costar Shirley. Jen dropped by Shirley's seat to offer a hug and congratulations. Her light look yesterday was a stark contrast to last weekend. Jennifer wore black leather to Sunday's MTV Movie Awards, where she picked up the 2012 Best Dirtbag honor.
