The lovebirds met in the fall while filming Deep Water in New Orleans, in which Affleck plays a man suspected of murdering his wife’s (de Arma) lovers. 

They’ve since been isolating together at the Gone Girl actor’s house in Los Angeles since returning from Costa Rica.

A source told People: ‘They seem to have a great time together. They order delivery food and groceries and only leave the house for walks around the neighborhood with their dogs. 

‘Ben looks incredible happy. They are flirty and goofy. Ana always has a huge smile around him.’
