David Letterman Shockingly Walks Out On Joan Rivers During Interview

Joan Rivers has once again proved she's a queen of comedy ... and of awkward interviews.

The comedian made headlines recently when she told CNN reporter Fredericka Whitfield to "shut up" and stormed off set. Then on Tuesday, July 8, after questioning Rivers about the walk out, David Letterman did the same thing to her.

Impressively, Rivers remained unfazed through it all, even finishing the segment by interviewing herself.

"Late Show with David Letterman" airs weeknights at 11:35 p.m. ET on CBS.
