“Gossip Girl” star Ed Westwick took out the trash the other night at the Barrow Street Alehouse in the West Village. The British actor stepped in to remove an unruly patron who knocked all of the drinks off the bar after the bartender refused to serve him Guinness. “Ed lifted him up by the collar and dragged him out,” a spy said, adding that after Westwick removed the “aggressive and violent” boozer, he calmly returned to his group of friends “like nothing happened.”
