Things got a little tense during a CNN interview with Joan Rivers.
Anchor Fredricka Whitfield asked about criticism over the cover of Rivers' new book, in which she was wearing fur.
Rivers was apparently not happy with the question, and went off on a tirade.
Since the book's release, Rivers has been criticized by animal rights groups. Protesters made headlines when they showed up at her book signing in New York last week.
Rivers ended up storming off camera and never returned to finish the interview.
