Affleck, 48, put on an animated display while on a balcony in The Big Easy as Ana, 32, showed of a sparkling diamond ring on her left hand.
It's unclear if the ring she's wearing is related to her character's performance or if the couple is planning to announce big news despite rumors the pair had separated after not being spotted together for more than a month.
Ana sported a classic black T-shirt with her short brown hair tied back into a French braid ponytail.
She flashed the massive sparkling engagement ring while chatting with Ben from the balcony of the New Orlean's set.
Ben went back and forth from crossing his arms over his chest to gesturing with his hands as he spoke to his lady love.
The couple have been known to show public displays of affection, but hadn't been seen together for some time in public.
Ana and Ben were last seen publicly on Oct. 15 in Los Angeles when he greeted her with a smile.

the duo were last seen August 20 during a flirty shopping trip to Nick Fouquet
boutique in Venice Beach, California, which was also the last time they showed
affection publicly.
