The brunette beauty flew to Detroit to be with her hubby, who is currently there filming the highly anticipated Batman vs. Superman: Dawn of Justice.
The two shared a romantic dinner at Bistro 82—a French fusion restaurant located in the Royal Oak suburb—and E! News has exclusively learned that the famous duo did their best to remain under the radar.
"Jen was wearing a black dress and Ben was in jeans with disheveled hair…They were walking slowly by and they seemed relaxed and in good spirits," an eyewitness tells us.
"They were walking very closely together. As they were walking out, Ben took a cigarette out and put it in his mouth and they walked out of the restaurant and he stopped and lit the cigarette. They then walked out together and headed down the street."
