The 36-year-old actress was photographed in a stunning bright yellow gown, which featured an extremely low neckline. Covering her shoulders with a black peacoat, Munn accessorized with a diamond choker, gold platform heels and edgy black lipstick.
The brunette beauty later took to Instagram, posting a selfie with Maria Sharapova, who also makes a cameo in the Ocean's Trilogy spin off.
"Filming a little late night cameo w @mariasharapova & she brought her own candy!" Munn captioned it. "She has her own candy line!!! #Goals."
While the full cast has yet to be announced, ET has learned that the film will feature a myriad of celebrities, including Kim Kardashian West, Kendall Jenner, Anne Hathaway, Sandra Bullock, Cate Blanchett, Rihanna, Sarah Paulson, Mindy Kaling and Helena Bonham Carter.
This also marks the first time Munn has been spotted since boyfriend Aaron Rodgers' father, Ed, broke his silence on the NFL pro's estrangement from the family, which came to light when his brother, Jordan, competed on the most recent season of The Bachelorette. In a new profile piece with The New York Times, the chiropractor noted that he doesn't "think it’s appropriate to talk about family stuff publicly," but "fame can change things."
Rodgers has reportedly not spoken with his family since 2014, around the time he started dating Munn. Hear more on that in the video below.
