An Etro-clad Jessica Simpson was the guest of honor last night at Us Weekly's annual Hot Hollywood party. This year's bash, held at the Eden nightclub, featured 2011's Style Icon, Jessica, along with other celebs like Lauren Conrad and a hot-in-red Camila Alves. American Idol's Pia Toscano looked right at home on the cream carpet, as did other attendees like Paris Hilton and Hayden Panettiere. Lauren showed off her fashion chops, too, wearing pieces from her new line Paper Crown. Jessica, however, gave props on Twitter to her clothing and makeup gurus, like Nicole Chavez and expressed some surprise at her latest honor. She said, "Style Icon of the Year, really? I'm not really that stylish, like to be honest with you. Like I wear my fiancé's Yale hoodie and a pair of sweat shorts that have been cut off, and Uggs, and Hanky Pankies, little pair of panties, you know? I'm not really that stylish, but I do know how to make a woman look beautiful, and when I want to look great, I know how to make it happen." The event was a big one for Ms. Simpson, though another celebration is on the horizon after Jessica and her fiancé Eric set a wedding date!
