18. BEST: Amy Adams showed off her fabulous post-preggers bod in a super lowcut Andrew GN mini and Christian Louboutin heels at the Producers Guild Award. 20. BEST: Leighton Meester brought out the bombshell for the Los Angeles premiere of The Roommate. The Gossip Girl, who is always a wild card on the red carpet (we will never be able to forgive her for that awful Marchesa jumpsuit) looked totally fab in a Pre-Fall 2011 Michael Kors collection black chiffon jersey leather cut out gown, which she paired with Harry Winston earrings and Brian Atwood heels.
