Kathy Griffin and late great Joan Rivers have a similar sense of humour so I think this will work. According to a report by TMZ, the comedian is set to replace Joan Rivers as host of Fashion Police. From TMZ : Kathy Griffin will be Joan Rivers’ replacement on “Fashion Police” … TMZ has learned. Sources connected with the show tell TMZ it’s a done deal. Kathy will join Melissa Rivers, Kelly Osbourne and Giuliana Rancic. We don’t know the fate of George Kotsiopoulos. We’re told the show will no longer be a weekly series. E! will roll it out during awards shows and other occasions as event programming. One silver lining … the drapes will now match the carpet for sure.
