Paris and Britney

They seem to do everything together these days, and were recently voted joint Worst Role Models. Now partyloving pair Britney Spears and Paris Hilton have been named the joint worst dressed women in showbusiness.

For the 47th year, stylist Richard Blackwell has released his list of the worst dressed celebrities of the year, and the two blonde Americans share the top spot. "Two peas in an overexposed pod," Blackwell said of the skimpy attire worn by the two, who he dubbed the "Screamgirls."

Another noteable name on Blackwell's list is Camilla Parker-Bowles, the wife of Prince Charles. Blackwell referred to Parker-Bowles as, "a royal wreck."

In the third spot on the list is American actress Lindsay Lohan, who Blackwell says has gone, "from adorable to deplorable."

Among the celebrities who were praised for their style by Blackwell were actresses Kate Winslet, Angelina Jolie and Helen Mirren, and singers Barbra Streisand and Beyonce Knowles.
