Jennifer Garner’s partner makes a public appearance following a surprising move by Ben Affleck that made him feel uneasy.

The first public appearance of Jennifer Garner’s longtime partner, John Miller, occurred following the release of a surprising video involving her and her ex-husband Ben Affleck, which reportedly made him uneasy.

While Affleck, 52, was away at the South by Southwest festival in Austin, Texas, Miller, 47, made it evident that he and Garner are still in a committed relationship by paying a visit to her residence in Brentwood on Sunday.

The CaliBurger CEO sported a grey t-shirt, blue jeans, suede brown boots and a trucker hat. 

Meanwhile earlier in the day, Garner, 52, was pictured filming scenes with a stuntman for her Apple TV+ series, The Last Thing He Told Me.

The actress was seen sitting behind the wheel, with a male co-star in the passenger seat. 

Recent events unfolded after a video showing an intimate moment between Garner and Affleck surfaced, leading to speculations about a potential rekindling of their past relationship and causing displeasure for his previous wife, Jennifer Lopez, 55.

In a video obtained exclusively by the Daily Mail, Affleck was seen tenderly embracing his ex-wife, and the mother of his three children.

The pair were paintballing at the Combat Paintball Park in Castaic near Los Angeles with their children, Fin, 16, and Sam, 13. Their eldest, 19-year-old Violet, is away studying at Yale.

An insider shed light about Miller’s feelings on Garner and Affleck’s close relationship, sharing: ‘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 and Jen have a unique relationship, especially for exes,’ the source added. 

Affleck and Garner tied the knot in 2005 and divorced in 2018. 

Garner has reportedly been dating Miller since 2018. 

Meanwhile Affleck premiered his new film The Accountant 2 at SXSW over the weekend.

He walked the red carpet with his co-star Jon Bernthal, 48, and his BFF Matt Damon.

Earlier this week it was reported that Garner is ‘deathly afraid of falling back in love’ with Ben, and still has ‘trust issues’ after he slept with their children’s nanny, Christine Ouzounian, now 37, a decade ago. 

‘She loves Ben but is worried that he will crush her all over again,’ a source told DailyMail.com.

‘She doesn’t want to heal another broken heart because it is just too much drama, plus she does not want their kids to see round two of their mom in a bad place with their dad.

‘So much could go wrong if they reunite.’

Last month insiders shared that Miller struggles with her relationship with Ben, and avoids talking about the actor where possible.

Garner had adopted the role of ‘marriage counsellor’ to her ex-husband and Lopez in the wake of their shock split last year, with some friends fearing she had been forced to ‘play mediator.’

The role did not sit well with Miller, who understands they have children, but reportedly doesn’t like sharing her.

‘John is trying to deal with Ben and Jen’s relationship by mostly staying quiet, but it’s very hard to do that,’ a source told DailyMail.com exclusively. ‘He knows that Ben has to be around as a father and he is more than OK with that, but he wants to be the man in the relationship.’

‘John only talks about Ben when Jen talks about Ben or when their kids talk about him. He doesn’t bring him up unprompted.’

‘John respects Ben, but less is more because John wants Jen for himself,’ the insider continued. ‘He still needs to figure out how to compartmentalise it all.’

Meanwhile Lopez is said to be ‘furious’ over cozy photos of Affleck and Garner, according to Page Six. An insider added that speculation about them rekindling their romance is ‘completely messing with her head.’ 

Lopez is reportedly ‘not happy with constantly seeing photos’ of the duo, a source told the publication. 

The photos have been like ‘salt in the wound’ to the Love Don’t Cost a Thing hitmaker.

Lopez and Affleck settled their divorce on January 6, however, court documents confirmed the marriage wasn’t legally dissolved until February 21.

The exes rekindled their romance in 2021 and got married in 2022, but called it quits in 2024.

Jennifer filed for divorce on August 20 – the date of their second wedding anniversary – and cited ‘irreconcilable differences’.
