Matt Damon stopped to pose for photos with fans and sign autographs as he left a NYC hotel yesterday. He's in the Big Apple promoting his upcoming Clint Eastwood project Hereafter as well as gearing up for his Thursday night cameo on 30 Rock's live episodes. He'll be reprising his role as Tina Fey's love interest Carol for two separate performances for the East and West Coasts. Last week Matt celebrated his 40th birthday with a low-key gathering with friends and family and later this month he'll be hosting another kind of party at his annual ONEXONE gala Oct. 27 in NYC. His wife Luciana's due date is also at the end of this month, and Matt recently revealed that they're expecting another baby girl!
