Sarah Jessica Parker in Pink & Red at David Letterman

Sarah Jessica Parker stopped for pictures when she arrived at the Ed Sullivan Theater in NYC today. She chose a bright red and pink Prabal Gurung ensemble for the appearance, which is just the latest stop on her press tour for I Don't Know How She Does It. SJP kicked off promotions in Russia last month and later popped up in London for a photo call. The actress brought her many fashionable looks overseas, donning a red Giambattista Valli gown and cape in Moscow and a floral Prabal Gurung dress during her time in the UK. There will be plenty of opportunities for SJP to show off her style since all the NY Fashion Week fun gets started tomorrow with Fashion's Night Out. Sarah Jessica will join the festivities with an appearance at Manolo Blahnik's Manhattan boutique, where they'll be serving the designer's favorite treat, milk shakes.
