Yesterday, the host of “Chelsea Lately” said a few unflattering things about Joan Rivers on Howard Stern's radio. Coincidentally, Joan was a guest on Howard's show today. As you can imagine, Joan ripped into Handler, saying, “She's an ordinary girl who was f*cking somebody high up in the industry and they gave her a break,” “wherever she is, she's drunk” and “don't you come after me, you whore.”
