If you thought Joan Rivers was outrageous before, wait until you see the antics of her royal ?highness? in the new season of her show, Joan & Melissa: Joan Knows Best? ?I smoke pot this season,? the comedian reveals to In Touch. ?It?s fantastic.? Apparently, Joan has smoked the funny stuff before ? with galpal Betty White. ?I mean, I went completely loopy, but it was fun!? says Joan.
