Sarah Jessica Parker smiled big as she arrived at her hotel in London today. She wore a yellow Chanel jacket, custom snakeskin Brian Atwood pumps, and carried a Louis Vuitton bag for her latest outing, which is part of her current press tour for I Don't Know How She Does It. SJP's already promoted the project in Russia, where she was decked out in a dramatic Giambattista Valli gown for a premiere and a sexy Prabal Gurung look at her photocall. She was dressed down at one point, though, when she had a run-in with an excited fan who tried to kiss her during an appearance outside of the Bolshoi Theater in Moscow. SJP will have plenty more chances to show off her fashionable side in the coming weeks since there are lots of interviews to do before the movie hits theaters in the US next month.
