The trio, along with other celebrities like Kirsten Dunst, showed off their style at the Christian Dior Haute Couture fashion show held during Paris Fashion Week on Monday in Paris, France.
The Mother! actress, who is also the face of the fashion brand, wore a sheer white mini-dress cinched at the waist, along with a pair of lace-up Dior sneaker-style boots. She finished off the look with a black and white knitted kimono and a matching wide-brimmed hat.
Joining her on the runway, which was held at Cloître Port Royal gardens, was Dunst, 35, who sparkled in a layered dress embroidered with a hearts and stars theme.
