The 67 year-old host showed the controversial comedienne what it is like dealing with a diva, only days after she stormed out of a CNN interview.
Joan Rivers finally got a piece of her on medicine.
David Letterman showed the comedienne what it is like dealing with a "diva."
Rivers appeared on the 'Late Show' to promote her new book 'Diary of a Mad Diva,' but during the interview the 67 year-old host suddenly stood up, took off his jacket and walked out.
"So, where are ya from? I'll just take over! I'll talk to me!" Rivers said when Letterman didn't return.
Several days earlier, the 81 year-old actress made headlines for storming out of a CNN interview after the anchor, Fredricka Whitfield, called Rivers out on her "mean" comments about celebrities' clothing on 'Fashion Police,' an E! reality show she hosts.
Obviously Rivers didn't appreciate this and never returned, but Whitfield later said she had "kept her microphone on and she continued to talk and drop some very unflattering four letter words."
While talking with Letterman, the controversial star described Whitfield as being "very judgmental, very nasty, very opinionated, very negative," before jokingly stating "It was like my wedding night, ya know?"
She also adamantly denied that the incident was just one big "publicity stunt to promote the book."
The Grammy Award-winner addressed the incident in a statement through her publicist to The Hollywood Reporter shortly after the incident.
"The CNN interviewer was a news reporter and not an entertainment reporter," she wrote. "She did not seem to understand we were talking about a comedy book and not the transcripts from the Nuremberg Trial. Every question was an accusatory one designed to put me on the defensive. She seemed to miss the point that Diary of a Mad Diva is simply a very funny book, and as Winston Churchill said, if you can make one person laugh, even for a minute, it's like giving them a little vacation."
