Joan Rivers under fire for Heidi Klum Holocaust joke

Has Joan Rivers gone too far (again)?

The comedian has sparked controversy over a joke she made about Heidi Klum in a sexy Julien Macdonald dress at Elton John's AIDS Foundation Academy Awards party.

"The last time a German looked this hot was when they were pushing Jews into the ovens," Rivers said of the German-born supermodel on Monday's episode of E!'s Fashion Police.

The Anti-Defamation League's director Abraham H. Foxman, a Holocaust survivor himself, said in a statement that the comments were "vulgar and offensive to Jews and Holocaust survivors."

The anti-Semitism watchdog group also criticized Rivers' Fashion Police co-hosts Giuliana Rancic, Kelly Osborne and George Kotsiopoulos, whom the statement says were "doubled over with laughter" after she made the joke.

When asked for comment, Rivers, who is Jewish herself, told The Hollywood Reporter, "My husband lost the majority of his family at Auschwitz, and I can assure you that I have always made it a point to remind people of the Holocaust through humor."
