A New York City Birthday Party Posted On August 26, 2007 Tristan and William’s friend Vivien celebrated her first birthday in Central Park. Vivien and dad (Doug) Greg and Lisa (due in October) practice with William Tristan chats it up at the sand bar (He is apparently attracted to older women) The party was a success. It looks like Tristan had a ball! Add a Comment Cancel replyYour email address will not be published.
