Joan Rivers Tells CNN Reporter To 'Shut Up' And Storms Off Set

Joan Rivers appeared on CNN Saturday to talk about her new book, but ended up yanking out her earpiece in the middle of the interview and storming off set instead.

Rivers was speaking to anchor Fredericka Whitfield, who had suggested that her "Fashion Police" commentary was "mean." The last straw for Rivers, though, apparently came when Whitfield asked her whether she was goading PETA activists by wearing a fur coat on the cover of her book "Diary of a Mad Diva."

"This whole interview is turning into a defensive interview," Rivers said. "Are you wearing leather shoes? Then shut up."

Rivers told Whitfield that all her questions had been "negative," adding, "You are not the one to interview a person who does humor, sorry," before walking off.
