Katie Holmes and Gisele Bundchen shared a red carpet last night to celebrate the Beauty Culture exhibit, which opens tomorrow, at the Annenberg Space For Photography in LA. It's a collection of images from various photographers, including a snap of Gisele herself, designed to make viewers question the pursuit of beauty. More Hollywood stars came out for the event, including Halle Berry, Ali Larter, and Amber Heard. Supermodel Gisele wrote that she was home in LA after a quick trip to the Amazon, where she was able to do the environmental work that's close to her heart. She posted on her blog, "What a magical place the Amazon is, and so full of history and legends . . . I’m here, sharing my special experience and feelings so we can all think about it. We need and we want to develop, but not at the cost of damaging the planet." The visit was one of philanthropy and fashion, as there was a Gisele Bundchen bikini sighting in Sao Paolo when she took the runway for the Hope Valentine's Day special collection show last week. Katie, meanwhile, is back on the West Coast after a stop in Chicago to honor Oprah and a stint in Florida. She got some swimsuit time in as well when she hit the pool with daughter Suri at her Miami hotel, near where husband Tom Cruise has been working on Rock of Ages.
