Matt Damon refused to talk to Jennifer Lopez about Ben Affleck at the after party for their new film Unstoppable, according to sources, who claim the actor made it clear that he will always have Ben's back. Lopez and Damon were seen holding hands during a private moment at the event held at the Toronto International Film Festival on Friday night. JLo and Matt had their heads close together and looked serious as they engaged in a reported 20 minute conversation. Lopez wanted to talk to Matt about her estranged husband in the wake of their divorce, but Damon was reportedly not having any of it. “Matt Damon shut down any attempt that JLo made to discuss Ben at the premiere,” a source told DailyMail. “It was her timing that was so awkward because she would have known that pulling Matt aside at the event to have an intimate talk was going to get picked up and go viral.”
