Adams, 42, attended the ceremony yesterday with her "Arrival" star Jeremy Renner director Denis Villeneuve and her husband Darren Le Gallo and daughter Aviana.
Adams thanked her director and co-star, saying Renner's friendship meant a lot to her as "it's great to have friendships in this funny town."
