"Jennifer Garner’s boyfriend, John Miller, allegedly issued a warning to Ben Affleck after he crossed the 'line' during their son Samuel’s 13th birthday celebration on March 2 at Combat Paintball Park in Castaic, California."
As the two were seen getting cozy with each other, it seemed that the CaliBurger CEO was not pleased about it.
With the struggles of The Accountant 2 star following his divorce from Jennifer Lopez, Garner has consistently supported her former husband, creating tension with Miller.
A Disrespect to Their Relationship
A source told Page Six that though Miller has always been supportive of Garner and Affleck’s co-parenting relationship, he feels the latter has crossed the line with his close bond with his girlfriend.
“John knows there’s nothing going on between Jen and Ben, but he doesn’t think those photos are a good look and feels it’s disrespectful to their relationship,” the insider continued.
The photos in question showed the 52-year-old actor grabbing the 13 Going on 30 actress around the waist as she pointed her paintball gun at someone, not in the picture.
Affleck pulled Garner in toward him, and it looked like she did not mind the embrace, making them look cozy as they laughed and talked to each other.
As the tipster added this resulted in Miller giving Garner “an ultimatum, he doesn’t want to see anything like that again or he has no choice but to walk away.”
So far, the three parties have yet to comment on the issue.
Jennifer Garner and John Miller’s Relationship
Garner and Miller have been in an on-and-off relationship since 2018, shortly after the former finalized her divorce from Affleck.
As a businessman, Miller has been keeping their romance private—out of the public eye. However, they are still seen together in public on some rare occasions, such as the premiere of Garner’s Apple TV+ series The Last Thing He Told Me in April 2023.
But though he showed his support, they did not pose for photos together. Despite that, People reported that Garner is “happy” with Miller even after Affleck’s divorce from Lopez.
A Complex Co-Parenting Dynamic
Garner and Affleck share three kids: Violet (18), Seraphina (15), and Samuel. Though they have been divorced since 2018, they have maintained a close co-parenting relationship.
The two tied the knot in 2005, separated in 2015, and filed for divorce in 2017 before it finally got finalized the next year.
According to reports, Affleck leaned heavily on Garner during his separation from Lopez, asking for advice and seeking emotional support.
Their relationship intensified after Lopez filed for divorce in August 2024. It seemed to even bring Affleck and Garner closer together with the moving of Violet into college at Yale University and celebrating his birthday.
While these events only show Garner’s commitment to keeping her kids close to their father, the speculations surrounding their closeness may have affected her relationship with Miller.
