Portman says in a statement that "as an individual who is proud to be Jewish, I will not be associated with Mr. Galliano in any way."
Both stars work with Christian Dior. Portman is spokesmodel for Miss Dior Cherie perfume. Galliano has been suspended as Dior's creative director pending an investigation into an alleged anti-Semitic incident in a Paris cafe last week.
Portman's statement was provided Tuesday to The Associated Press after a video posted online showed Galliano, in a different incident, drunkenly telling a cafe patron, "I love Hitler."
