Aw, Justin Theroux!

"Not to be corny, but it's true," he said. "So I constantly say that."

How nice!

Theroux is actually an avid gamer, and told us his mancave is really just "a little office I play in and a little chair that's set up."

So, does Aniston ever join in?

"No. Jen does not play the game, and doesn't understand why I play the game, but she allows me to," he said. "She's nice enough to let me go away for a couple hours a couple times a week and play."
