Joan Rivers wishes there were more female celebrities who used their stardom to set a good example for women, instead of making themselves look like fools.

Joan has hit out at Jessica Simpson and Paris Hilton - calling them dumb blondes.

Instead of bashing a celebrity's fashion wear, this time Joan Rivers went after the most talked about celebrity baby.

The talk show host - who's had just as much plastic surgery as Julie Newmar AKA Catwoman where she could easily be mistaken as her twin - singled out the five-month-old daughter of Tom Cruise and Katie Holmes during her comic routine at top venue Cutting Room, in Manhattan, on Wednesday night.
