Ben Affleck Has Spirited Conversation with Jennifer Lopez at Movie Premiere

Ben Affleck tends to wear his emotions on his sleeves — and he seemed to be doing exactly that at Jennifer Lopez‘s premiere … where he looked a bit fired up while talking to his wifey.

The famous couple showed up in their designer duds to the Dolby Theater Tuesday night for J Lo’s ‘This Is Me … Now’ flick/music video — and everything seemed pretty hunky-dory at first. They posed for pics, smiled and went about their business like normal … all smiles.

However, at some point while inside … the mood appeared to change, and so did Ben’s.

Check out this video, obtained by TMZ … J Lo and Ben were having a private convo in the lobby of the large, crowded auditorium — and it looks like the two of them were engaged in a pretty engrossing chat, at least from Ben’s side anyway … dude had a lot to say.

Hard to say what exactly he might’ve been communicating here — you could say he looks a little annoyed, but he also just comes across as spirited. Jen, meanwhile, is totally chillin’.

Eventually, she turns away and talks with others … while Ben continues to speak with a guy.

As for the movie experience itself … everyone seemed to love it and was really into seeing J Lo’s life story on the silver screen. The leading lady herself even got onstage and gave a speech, bringing herself to tears as she talked about producing the biopic, of sorts.
