WEEK OF MARCH 10, 2009 Sometimes two heads are better than one, especially when it comes to dressing for the red carpert (there is a good reason celebs hire stylists; it never hurts to have a second opinion!!!) Co-stars Emily Blunt and Amy Adams showed what their pretty little heads could come up with as they graced the red carpet at the LA premiere of their new comedy, Sunshine Cleaning. Emily selected a detailed Basil Soda dress and nude peep-toe pumps while Amy choose a white Burberry pant suit accented by a black cami and multi-strand necklace. Both co-stars looked so great in their respective red carpet outfits that when we put our heads together we were unable to select just one for our Best Dressed Celebrity of the Week. Our two heads think they both deserved the honor!   BEST CHAINMAIL Diane Kruger showed us she's one tough chick in a Roberto Cavalli fur shouldered dress at the Roberto Cavalli Paris Boutique Opening during Paris Fashion Week.   BEST GODDESS Nicole Richie looked absolutely radiant adorned in bangles at the launch of her House of Harlow 1960 jewelry collection at Kitson in L.A.   BEST OP ART Svelte Victoria Beckham looked even slimmer in this optical illusion of a dress by Alexander McQueen while out for dinner in Milan.   BEST FRINGE Rachel Bilson was in full swing while running errands around L.A. in this funky flesh-tone fringe dress and gray opaque tights.
