Fashion Police: The Winners Are Helen Mirren and Kate Middleton

British beauties wind up as the best-dressed and worst-dressed stars of last week!

It's a British invasion!

Last week, Dame Helen Mirren made a very rare fashion misstep, showing up at the British Comedy Awards in this Dolce & Gabbana star and lace hot mess. We never thought we'd see the day, but the actress nabbed the worst dressed of the week title.

Meanwhile, England's newest duchess, Kate Middleton, was easily best dressed of the week in her stunning black velvet Alexander McQueen gown and blingin' jewels. Well done, Duchess Catherine!
