To recreate fashion's top event, the production called on Kim Kardashian West, Kendall Jenner, Helena Bonham Carter, Olivia Munn, Zayn Malik, Hailey Baldwin, Maria Sharapova, Katie Holmes and more to film fake grand arrivals to the gala.
ET has also learned that James Corden makes a cameo as an insurance investigator who is suspicious of the movie's stars -- Sandra Bullock, Cate Blanchett, Rihanna, Anne Hathaway, Sarah Paulson and Mindy Kaling.
"The cast is phenomenal, and I'm excited to see what those women do with it," Matt Damon told ET in November. "It's going to be fun."
Damon returns to the franchise as former pickpocket Linus Caldwell, but will George Clooney also join the heist film? ET did get a promising clue when the character name Danny Ocean was spotted on a call sheet, but nothing has been confirmed yet.
Newcomer Holmes dished to ET about the movie earlier this month.
"I'm a fan of all the Ocean's movies," she said of what drew her to make a cameo in the film. "So, I'm happy that it has so many amazing women in it. It's really so much fun being a part of."
Kardashian West filmed her cameo in a floor-length white lace gown and white fur jacket. The reality star was back in NYC after a recent trip to Dubai, where she made her first official public appearance since her harrowing Paris robbery in October. In Dubai, the Keeping Up With the Kardashians star also served as a model for makeup artist Mario Dedivanovic in his masterclass, and also spent time riding four-wheelers and visiting local schools.
