No one’s more pleased about Ben Affleck ’s success than his ex-girlfriend Jennifer Lopez (inset). Watching Affleck win best director and “Argo” best picture at the Golden Globe Awards made JLo smile. ‘‘[‘Argo’] was a great movie,” the 43-year-old singer said during a sitdown with Ellen DeGeneres. “They were really hard on us in the press when we dated back in the day. On movies and things like that. So it was a nice moment. It was nice to see him have that moment. I was really happy for him.” It’s true that the press was hard on Bennifer, but it wasn’t entirely undeserved. They did, after all, make “Gigli” and “Jersey Girl” together.
