The 'Leftovers' actor, who married the 46-year-old actress in August, admits she gets "upset" when he spends hours playing 'Call of Duty: Black Ops 3' at their Bel Air home in California.

Asked if they play the military science fiction game together, the 44-year-old star said: "Wifey does not play.

"Wifey is like, 'Where are you?' She still doesn't see it as a social app. Like, I am hanging out with my friends - technically - and she's like, 'No. You are sitting there watching a TV playing a game.' She's not understanding!"

But Justin isn't surprised that Jennifer doesn't share his love of gaming.

He told E! News: "Well, it looks weird when you walk in and they're just sitting there screaming into a headset and they're killing each other. I'm going to war, and she's not understanding. Then I come back from war and she's upset."

But he insists his hobby doesn't really cause any problems between them.

He said: "She knows that I love it, so she's very tolerant."

The 'Zoolander 2' writer recently confessed he loves being married to the former 'Friends' star.

He said: "It's fantastic. Something really does shift in a wonderful way and it refocuses things and in a weird way, it was a long time coming."
