Its shocking, anti-Semitic content puts him on a collision course with the proudly Jewish Portman.
She was asked about Galliano's comments in the backstage pressroom after her Best Actress Academy Awards win, but was prevented from answering by the event moderator.
The U.K.'s Sun newspaper has obtained film of earlier remarks made by Galliano that are allegedly similar to those that resulted in his arrest, and subsequent suspension by the fashion house on Friday.
In this disturbing video he declares, "I love Hitler!"
Apparently drunk at the La Perle brasserie in Paris, he tells those filming the exchange, "People like you would be dead today. Your mothers and forefathers would be (expletive) gassed."
The video foreshadows an ugly incident that allegedly happened in Paris late last week, which resulted in Galliano being charged by police with assaulting a couple in a cafe.
While the people he was speaking with in the earlier Sun video were not in fact Jewish, the face of Dior's new perfume, Natalie Portman, was born in Jerusalem. She is a steadfast supporter of Jewish causes and in 2003 received the Israel Cultural Award.
In 2005, she told author Abigail Pogrebin in "Stars of David: Prominent Jews Talk About Being Jewish": "I have a very close friend who lately has this European, anti-Israel way of thinking, and it's very hard to have conversations with him. ... (Being Israeli has) become a much bigger part of my identity in recent years because it's become an issue of survival."
It remains to be seen how this development will affect her relationship with the European luxury brand. A spokesperson for Dior was not available overnight for comment.
