Kate Hudson wore a Barbara Bui ensemble and Cartier jewelry as she joined her The Reluctant Fundamentalist costar Riz Ahmed and director Mira Nair at a Q&A session for their film at the New York Indian Film Festival yesterday. Kate was coming off a busy afternoon, having just made an appearance on The Late Show. For her chat with David Letterman, Kate wore a leather skirt and a neon pink t-shirt. Kate has been hitting the press trail hard for her new film, which will open in limited release tomorrow, April 26. She made an appearance on Good Morning America earlier in the week too, praising Mira for supporting her on the film while she was still breastfeeding her son Bingham. Kate also premiered the new project at the Tribeca Film Festival alongside her fiancé Matthew Bellamy. While she has been putting in a lot of hours to promote her new flick, Kate isn't showing any signs of slowing down soon — she is set to costar alongside James Franco in Good People, which will begin filming in London in May.
