A fight between Margot Robbie and Samara Weaving erupted during the Memorial Day fireworks show last night. One woman accidently bumped into the other while waiting for drinks at the bar. After an exchange of words, a drink was thrown, and an all-out brawl started between the Aussies. Once the fight made its way to the ground, Chace Crawford and Ryan Gosling stepped in to break things up. Chace pulled Margot off of Samara and tossed her over his shoulder, while Ryan lifted Samara up from the ground and held her back to prevent the fight from continuing. Both women were treated separately for minor scratches, scrapes, and bruises. Neither were available for commenting.
