The reality TV star and her half-sister Kendall Jenner will make cameo appearances in the film.
It will be the fourth movie in the Ocean's franchise in 17 years - confusingly coming after Ocean's Eleven, Twelve and Thirteen.
Kardashian and Jenner were photographed in New York on Monday after reportedly filming their cameos.
The pair will apparently appear in scenes set at a fictional gala being held at the Metropolitan Museum of Art.
One scene in the film features a jewel robbery at New York's annual Met Gala - an event packed with celebrities.
