This isn't gonna be pretty. Sources confirm that Charm School headmistress Mo'Nique has just been cast on Ugly Betty as a weekend receptionist at "Mode" who's got it bad for good-guy Henry. So far, the comedienne is only scheduled to appear in one episode, to air in late November or early December, but please - how are they gonna be able to resist bringing her back for more?
