Guess she wasn't having any of it!

The always opinionated Joan Rivers usually has lots to say, but that certainly wasn't the case on Saturday during an interview with CNN's Fredericka Whitfield.

The comedian/TV personality was promoting her new book, Diary of a Mad Diva, but took offense at Whitfield's comment on how her show Fashion Police is "mean."

"It's not mean," Rivers said. "I tell the truth. I'm sure I say the same things your viewers say to their friends sitting next to them on the couch."

The comments kept coming from Whitfield, who also mentioned how the jokes about certain topics in her book might appear to be "off-limits," to which Rivers responded, "Life is very tough, and if you can make a joke to make something easier, and funny, do it." However, things took a turn for the worst once Whitfield commented on her fur coat wearing on the book's cover.

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

"I'm going," Rivers continued, pulling out her earpiece. "All you've done is negative … I've made people laugh for 50 years. I am put on earth to make people laugh." As she stood up to leave, Rivers quipped,"You are not the one to interview a person who does humor. Sorry."

What a way to end an interview!
