Pop star Britney Spears and her new pal Paris Hilton are sharing the number one spot on Mr. Blackwell's 47th annual Worst Dressed Women List. The designer unveiled his selection yesterday, branding the pair "two peas in an over-exposed pod" and "style-free and fashion deprived." Scoring the third spot was 20-year-old Lindsay Lohan, who Blackwell said went "from adorable to deplorable." Also targeted was 57-year-old Meryl Streep, who played a fashion editor in The Devil Wears Prada. Blackwell's selections for best-dressed include Kate Winslet, Angelina Jolie and Dame Helen Mirren.
