What famous person did Joan Rivers have a major falling out with?

Johnny Carson mentored Joan Rivers for many years, making her a regular guest host. In 1986, Fox Television Network announced The Late Show Starring Joan Rivers. Carson learned of the show from Fox and not from Rivers herself. The pair reportedly never spoke again and Rivers was banned from appearing on the Tonight Show. This was respected by Carson's first two successors Jay Leno and Conan O'Brien. However, Rivers made a brief appearance on new host Jimmy Fallon's first episode in February, 2014 and again March 27, 2014 as a guest.
