Video: Joan Rivers Slams Jay Leno Who Kept 'Tonight Show' Ban

YA GOTTA LOVE HER! Joan Rivers stopped by Bravo's "Watch What Happens Live" Thursday night to talk red carpet fashion, Whitney Houston, and Betty White -- but things heated up when Jay Leno was brought up.

Rivers, who has been in a feud with "The Tonight Show" since the early 80s when then-host Johnny Carson blacklisted her for leaving to host her own show, is just now breaking back into the late night scene. Hosts like Jimmy Fallon and David Letterman are inviting her onto their programs, but Leno is still holding tight with the show's traditional no-Rivers policy.
