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.
The sharp-tongued comedienne wrote a letter to her university alumni appealing for donations to her old sorority and snidely used the two blonde stars as examples of stupid young women.
According to the New York Post, Joan wrote to Barnard alumni, "We must support women who have a sense of confidence and self-worth. Where have all the smart girls gone? That is a hard question to answer in an age where Jessica Simpson and Paris Hilton pass as intellectuals."
Joan also took a swipe at the women she was writing to by suggesting they would have to dig in their husband's pockets for donations, as they did not have their own money to give.
She told them, "Go through your husband's wallet, and give everything in it."
Hotel heiress Paris has earned millions with her business ventures which include designing her own range of jewelry and accessories, launching her own nightclub chain, modeling, acting and releasing a pop album.
Jessica Simpson has a successful music and film career and has also released her own line of beauty products.
