AceShowbiz - Jennifer Garner's long-term boyfriend, John Miller, was seen for the first time since a video surfaced showing the actress sharing a tender moment with her ex-husband, Ben Affleck. Miller was seen dropping by Garner's house in Brentwood on Sunday, March 9.

Miller, the 47-year-old CEO of CaliBurger, sported a grey t-shirt, blue jeans, suede brown boots, and a trucker hat, all while looking visibly composed amidst the speculation.

Meanwhile, earlier in the day, Garner, aged 52, was seen filming scenes for her Apple TV+ series, "The Last Thing He Told Me". The actress looked focused as she worked with a stuntman on set.

The sighting came amid speculation that Garner and Affleck might be rekindling their romance. This chatter was buzzing after Affleck was caught on camera affectionately hugging Garner during their son Samuel's 13th birthday paintball outing.

An insider disclosed, "Does it bother John when he sees the two of them being touchy-feely? Sure. It would get to anyone, but this is nothing new."

"Ben loves Jennifer more than any woman he has ever loved besides his mom. He has accepted they cannot be together but will always flirt with Jennifer," revealed the insider.

Indeed, Affleck and Garner, who were married for a decade before their 2018 divorce, have always maintained a close, amicable relationship for the sake of their three children: Violet, 19, Seraphina, 16, and Samuel, 13.

Seemingly unfazed by the rumors, Ben Affleck, 52, has also been busy with his own project. He recently appeared at the South by Southwest festival in Austin, Texas to premiere his new film, "The Accountant 2".

Sources close to Garner claim that she is content with Miller and is not interested in reigniting a romance with Affleck. "Ben is not Jen's boyfriend, nor is he her husband anymore. John [Miller] is her partner, and she is happy in her relationship," reiterated a source.

Meanwhile, Jennifer Lopez is reportedly "furious" over the cozy photos of Garner and Affleck, feeling the images are "salt in the wound." Affleck and Lopez rekindled their romance in 2021 and married in 2022 but separated two years later, finalizing their divorce earlier this year.

Meanwhile, Garner's boyfriend, Miller, is handling the situation with poise, though sources say it can be challenging, "He doesn't feel threatened in terms of Jen ever getting back with Ben, but at the same time it's hard not to feel jealous when it's clear they have a strong connection and friendship."

For now, it seems like all parties are trying to navigate their complex relationships while maintaining their personal boundaries and respect for each other.
