This weekend marks the start of awards season, and, last night, celebrities got a chance to practice dressing up before the first big red-carpet hoopla on Sunday. Stefano Tonchi hosted a star-studded Golden Globes bash at Chateau Marmont that drew everyone from Amy Adams and Jessica Chastain to Reese Witherspoon, Cara Delevingne, Naomi Campbell, and Eddie Redmayne, while Liev Schreiber, Naomi Watts, and Edward Norton chose to attend Audi’s big pre-party. Earlier in the week, Carrie Brownstein, Questlove, and Jessica Williams turned up to celebrate the second season of Broad City; Arianna Huffington hosted lunch with Jennifer Aniston and Justin Theroux; and Allison Williams brought her dad to the Girls season-four premiere after-party, where they were joined by Jenna Lyons and Jon Hamm.
