Sarah Jessica Parker was in a bright dress from Prabal Gurung today for an I Don't Know How She Does It photo call at London's Soho Hotel. She arrived in England a few days ago, fresh off a trip to Russia, and was in white for a photo shoot at Claridge's yesterday. Following today's press event, she threw on some jeans and heels to take in the sights of the city. She also had time for a Twitter interview with Glamour UK. SJP revealed her fashion icons, saying she has, "So many. Ingrid Bergman, and the way Kate Moss dresses, and the Duchess of Cambridge!" SJP will head home to the US soon to promote the picture before its Sept. 9 release — stay tuned next week for our chat with the star! Early November will see Sarah Jessica travel to Australia for one last promotional leg. She'll even attend the Ladies Day of Melbourne's Spring Racing Carnival, on Nov. 3, along with Elizabeth Hurley and her boyfriend, Shane Warne.
