"It's so weird that we're all standing here," Witherspoon said. "It's really fun, but it feels unfair that we spend so much time working together, and then we get to go to this fun party together, and we're all like trying to be serious actresses, and it's just like, we have the best time."
"We're all like really good friends. I want to run and hug Zoe [Kravitz]," she added. "It's really fun."
