Wearing a summery yellow dress, black belt and heels, Katherine left the Ritz Carlton Hotel in New York this afternoon where she stopped to take some photographs with fans waiting outside. Her destination was the Ed Sullivan Theatre, to make a guest appearance on The Late Show with David Letterman. She posed for photographers outside the venue before and after her interview, which will air later this evening.
