The 48-year-old Justice League star looked annoyed and miserable following his romantic dinner with the singer and her 13-year-old.
Affleck was photographed appearing tense and agitated while awaiting shutterbugs snapped away at the trio as the group exited Craig's in West Hollywood.
The Academy Award winner's expressions are strange considering his restaurant of choice is the most sought-after celebrity hotspot in all of Los Angeles.
Anyone who wants to be photographed knows that Craig's is the place to be because it's always swarming with A-listers.
J Lo seemed to pick up on the tension and didn't seem amused.
Affleck didn't dress up for the occasion either. He wore casual black jeans, a dark-colored sweater, and sneakers.
As for the Love Don't Cost a Thing singer, she appeared laid-back in white wide-legged pants and a light green tank top. J Lo spiced up her date night attire with several gold necklaces and nude heels.
Looking like a doting mom, J Lo made sure her blue-haired daughter got in the car safely before the trio drove away.
Leaving the restaurant was a whole other story. Affleck sat in the driver's seat and cocked his head back while trying to slowly make his way passed paparazzi.
Publicity for the couple dubbed Bennifer is nothing new; in fact, Radar was told their entire Saint-Tropez vacation was a planned PR tour.
We were told J Lo and Affleck's trip was actually a twofer, with the couple agreeing it would be the perfect opportunity to showcase their on-again relationship to the world.
The Hustlers actress even brought her entire team -- including a professional photographer, her manager, and two publicists -- to make sure their PDA parade goes off without a hitch.
They came in handy when they helped her avoid an awkward run-in with her ex-fiancé Alex Rodriguez, who happened to be vacationing in the same place at the same time.
Speaking of A-Rod, it appears he's let the saltiness go when it comes to his bitter breakup with J Lo.
He recently poked fun at their failed engagement while posting about her for the first time since their split in April.
