Joan Rivers' Heidi Klum Holocaust Joke Offends Survivors: Comedian Refuses to Apologize to Anti-Defamation League for Vulgar Oscar Gown Bash [PHOTO]

Joan Rivers, comedian and Fashion Police host, allegedly highly offended Holocaust survivors with her "vulgar" joke aboutt Hedi Klum's Oscar party gown, and she refuses to apologize for it.

On Monday's episode of E!'s "Fashion Police," Rivers and her co-hosts were discussing Oscars fashion when they brought up the 39-year-old former Victoria's Secret model's "revealing" gown that showed off her cleavage, hugged her curves, and turned lots of heads at Elton John's Oscar party, notes Huffington Post.

Klum, a native of Bergisch Gladbach, Germany, wore a plunging gold Julien Macdonald dress to the annual AIDS Foundation Academy Awards viewing party in West Hollywood on Sunday, Feb. 24, as noted by Us Weekly. A lot of people are complimenting my dress, but they aren't looking into my eyes when they say it," the 39-year-old supermodel told The New York Post's Page Six of her "cleavage-baring" look.

"The last time a German looked this hot was when they were pushing Jews into the ovens," Rivers, a Brooklyn-born child of Russian Jewish immigrant, joked during her show.

This "vulgar and offensive" Holocust punch-line was apparently not very funny to some viewers and caused much controversey. The Anti-Defamation League blasted Rivers for it.

"There are certain things about the Holocaust that should be taboo. This is especially true for Jews, for whom the Holocaust is still a deeply painful memory. It is vulgar and offensive for anybody to use the death of 6 million Jews and millions of others in the Holocaust to make a joke, but this is especially true for someone who is Jewish and who proudly and publicly wears her Jewishness on her sleeve." stated the ADL director and Holocaust survivor Abraham Foxman, regarding River's "outrageous" joke.

The League asked the network to remove the Fashion Police segment from future broadcasts and requested an apology from the comedian. Joan's obstinate response was, "For what?"

"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," Rivers said in a statement, via The Hollywood Reporter.  Her late second husband, Edgar Rosenberg, reportedly committed suicide in 1987.

According to CNN, the Fashion Police host feels that the critics should focus on people who have anti-Semitic views and not on a joke that reminds people of the Holocaust.

This isn't the first time Rivers has been targeted by the Anti-Defamation League, states Us. In the fall of 2012, she compared Costco to Nazi Germany when the wholesale club refused to sell her book, I Hate Everything . . . Starting With Me.

Did Joan Rivers cross the line with her punch-line about Heidi's "hot" look, or is the ADL taking this ordeal a little too far?
