During the REELZChannel portion of the 2017 Winter Television Critics Association Press Tour on Friday, the Kennedys: After Camelot star chatted with ET's Leanne Aguilera about her role in Ocean's Eight.
"I'm a fan of all the Ocean's movies. So, I'm happy that it has so many amazing women in it, so many amazing actresses. It's really so much fun being a part of," Holmes gushed. "I play myself. It's just a cameo."
Holmes isn't the only celebrity to have a cameo in the movie, which reportedly centers around a heist at the annual Met Gala in NYC. Matt Damon -- who starred as pickpocket Linus Caldwell alongside Brad Pitt and George Clooney in Ocean's Eleven, Twelve and Thirteen -- told ET that he too will make an appearance in the film.
"I'm doing a little bit in the movie," Damon shared. "I haven't read it yet, but the cast is phenomenal and I'm excited to see what those women do with it. It's going to be fun."
ET also can confirm that Late Late Show host James Corden will make a cameo in the film. Ocean's Eight hits theaters on June 8, 2018.
