The pair was spotted at an event honouring Pete Hamill at NYU's Kimmel Center for University Life on February 25, reported the New York Post.
"Allen was heckled earlier this month by an audience member at Lincoln Center, but this time no one bothered him. He only chatted with those at his table, a source said.
The 'Blue Jasmine' director apparently attended the event because Hamill's brother Brian has been unit photographer on 26 of his films.
