The fun continued inside Siren Studios in LA last night for the stars who attended the Vanity Fair and Juicy Couture event cohosted by Shailene Woodley, benefiting her All It Takes charity. Jessica Chastain made the rounds in her daring Alexander McQueen ensemble, chatting with friends like Marcia Gay Harden and Kelly Lynch. Jessica's on the current cover of Vanity Fair, along with fellow attendees like Shailene and Paula Patton. Paula made the rounds and said hello to pals like Ali Larter and Dania Ramirez. The pre-Oscars event was one of the many taking place in and around Hollywood in the run-up to Sunday's ceremony. Jessica is in the running for her first-ever statue — do you think she'll win best supporting actress for The Help?
