Kate Hudson carried her son Bingham Bellamy as they left their NYC hotel today. Her casual outing with her almost-2-year-old comes on the heels of a busy day and night yesterday. Kate appeared at the New York Indian Film Festival last night to take part in a Q&A with her The Reluctant Fundamentalist costar Riz Ahmed and director Mira Nair. Earlier in the day, she swung by to chat with David Letterman on The Late Show, where she described her older son, Ryder Robinson, as a "laid-back, cool, sort of poetic type" and Bing as a "fireball." Now that Kate's busy week of promotional stops in the Big Apple is winding down, she will soon head back to London and begin filming her latest project with James Franco, titled Good People.
