Ben Affleck and Ana de Armas stroll arm in arm as they take a quarantine break to walk their dogs

They went public with their relationship during a romantic getaway to Costa Rica and Cuba.

And ever since touching back in Los Angeles as quarantine started, Ben Affleck, 47, and Ana de Armas, 31, have been inseparable.

The acting couple were spotted with their arms linked as they took their dogs out for a stroll around the neighborhood on Saturday.

Ben looked casual in a gray–blue ‘Believe In Boston’ T-shirt with dark blue jeans and black sneakers.

Ana was similarly casual in a white T-shirt that was partially tucked into her black jeans. 

Despite LA’s recent warm weather, she had a beige cardigan draped over her shoulders, and she rounded out the look with white open-toe heels.

The couple didn’t bother with social distancing as they’ve been living together amid their coronavirus quarantine, but they both covered their faces with masks.

Ben and Ana first met on the set of their upcoming thriller Deep Water last fall.

A source told People that they had an ‘instant connection’ while filming the movie.

‘They had great chemistry right from the start,’ the source said of Ben and Ana, who play a couple in the movie from Fatal Attraction director Adrian Lyne.

‘Ben always seemed very relaxed and happy around Ana, but at the time there were no signs of romance. He was very focused on making a fantastic movie.’

The two took their relationship public in March when they were seen enjoying a vacation in Costa Rica and Ana’s native Cuba.

Ben later revealed he’d shot some of the photos the actress posted to Instagram when he playfully asked for a credit in the comments. 

The couple star as a married couple who have fallen out of love in their upcoming film.

Despite seeming to not care about her romantic trysts, Ben’s character plays a dangerous game of cat and mouse with her suitors.

The story, based on the novel of the same name by Patricia Highsmith, was previously adapted into the French film Eaux Profondes starring Isabelle Huppert and Jean-Louis Trintignant. 

When Ben isn’t spending time with Ana, he’s usually with his three children, Violet, 14, Seraphina, 11, and Samuel, eight.

He shares the children with his ex-wife Jennifer Garner, 47, whom he was married to from 2005 until their separation in 2015.

Despite the breakup of their marriage, both parents have managed to maintain a positive relationship, and they regularly come together to support their children at school events and special occasions.
