According to the New York Times, the actress released the following statement on Monday:
"I am deeply shocked and disgusted by the video of John Galliano's comments that surfaced today. In light of this video, and as an individual who is proud to be Jewish, I will not be associated with Mr. Galliano in any way."
The Times adds, "it was not known how Ms. Portman's contract with Dior might be affected." Although Portman was expected by fashion insiders to hit Sunday night's Oscars in Dior, she donned Rodarte instead -- her stylist Kate Young told the newspaper that had been the plan since the beginning.
