Joan Refuses To Apologize! Rivers Slammed For Holocaust Joke About Heidi Klum

Joan Rivers has never met a highly offensive joke she didn’t like!

With her razor sharp wit the comedienne has earned the wrath of the Anti-Defamation League after making a shocking Holocaust quip about Heidi Klum -- but in true Joan style, she isn’t backing down or apologizing!

“The last time a German looked this hot was when they were pushing Jews into the ovens,” Joan joked about Heidi’s stunning Oscars night look where she wore a Julien Macdonald gold gown with a plunging neckline showing off her supermodel body.

The 79-year-old comedienne, who is Jewish, made the joke on her E! show Fashion Police during a segment about Elton John’s AIDS Foundation Academy Awards party -- and the ADL was quick

to condemn her off-color quip.

“Of all people, Joan Rivers should know better. This remark is so vulgar and offensive to Jews and Holocaust survivors, and indeed to all Americans, that we cannot believe it made it to the airwaves,” Abraham Foxman said.

“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 six 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.”

Joan has refused to apologize for the joke, releasing a statement to ABC News saying: “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 is known for her edgy, often offensive humor, and is usually non-apologetic -- but she does sometimes censor herself-- as RadarOnline.com previously reported  ,  Joan told Howard Stern back in 2011 that she once ditched a joke about First Lady Michelle Obama from her stand-up routine – because she feared she’d be accused of racism.

Recalling the wisecrack, the comedy legend said: “We used to have Jackie O now we have Blackie O!”

Rivers said she wrote the joke in reference to Michelle's fashionable dress sense and was comparing her to former First Lady Jackie Kennedy Onassis.

“I thought it was a funny complimentary joke when she first came (to the White House),” Rivers told Stern.
