Although the couple spent the holiday together last year at Michael Rubin's annual star-studded white party in the Hamptons, they have spent their summer largely apart as they face tension in their marriage.

While Affleck's latest project, The Accountant 2, a sequel to his 2016 action film, recently wrapped filming in Los Angeles, the actor, 51, chose to stay on the West Coast for the holiday. He was photographed heading to his office on Wednesday, July 3.

However, Lopez and Affleck, who wed in July 2022 have continued wearing their wedding rings.

Their time apart comes after an insider told PEOPLE in June that the two are "focused on their separate lives" and “don’t have any summer plans together." Affleck also recently moved all of his things out of the couple's Beverly Hills mansion.

“Ben continues to live at the Brentwood rental. He’s been there for about two months now. He seems okay. He’s been at his office every day and seems focused on work. He’s also spending time with his kids," a separate insider told PEOPLE in June.
