It’s been a whole week since we heard a peep out of Upper East Side’s queen of mean, Joan Rivers, and her resident rival, Elizabeth Hazan. For the past month these two brash divas have been locked in a public standoff over Hazan’s failure to pay $200,000 in condo fees. For condo board president Rivers, this just isn’t good enough. Her reaction: allegedly putting glue in Hazan’s locks and destroying her cable box. Hazan is now suing Rivers for $15m for the supposed vandalism.
