Jennifer Garner was glimpsed with a glittering ring on her left hand fourth finger this weekend, amid her long-running romance with businessman John Miller.

The 13 Going on 30 star first began dating the CaliGroup CEO in 2018, three years after her separation from her ex-husband Ben Affleck, with whom she shares three children — Violet, 19, Finn, 16, and Samuel, 13.

Though Garner and Miller briefly split in 2020, they reportedly reunited the following year and have largely kept their relationship out of the spotlight ever since.

Despite rumors that she and Ben were growing close again in the wake of his divorce from his latest wife Jennifer Lopez, she and Miller appear stronger than ever, even being photographed sharing a kiss in April 2025.

Rumors have been swirling that Miller has moved in with his movie star girlfriend, and he poured fuel on the fire when he was spotted outside her mansion in May.

Now Garner has been spotted out and about in Los Angeles with a sparkling bauble on her left hand, intensifying the speculation about her relationship status.

Daily Mail has contacted Garner’s representatives for comment.

She cut a characteristically elegant figure in a dark blouse tucked into high-waisted jeans, teamed with a silver cardigan, a leather handbag and tortoiseshell shades.

‘John is basically living with Jennifer,’ a source told UsWeekly this May, noting it was only ‘part time.’

The site also claimed he moved out of his Los Angeles home after the wildfires ravaged several neighborhoods in the Southern California city, and he has yet to find a new pad.

‘He has an office in L.A. and splits his time between staying there and at Jennifer’s home,’ the source said.

This comes after DailyMail.com confirmed in mid-March that Garner and Miller are still going strong, with a source spotting them looking cozy on a date night.

The couple were seen ‘holding hands and kissing’ and being ‘very cute with one another’ as they strolled through the Brentwood Country Mart in Los Angeles.

The PDA-filled outing took place in the evening, according to the eyewitness.

‘They are still going strong and appear to be doing really well,’ the source shared.

‘They looked happy and at ease, like a married couple that is thriving. They laughed and smiled at each other. Very cute.’

The insider added that both were dressed down for the casual date. ‘She had no makeup on, her hair down. He wore a coat and jeans.’

‘There was a lot of affection between them,’ the source continued. ‘They held hands and kissed — just a very normal couple with no Hollywood weirdness.’

Miller, a Stanford Law School graduate, now serves as chairman and CEO of CaliGroup, a tech conglomerate that not only owns the CaliBurger restaurant chain but also invests in innovative ventures in robotics and artificial intelligence.

He also heads CaliGroup’s portfolio company, PopID, which focuses on facial recognition payment systems.

Despite his impressive resume, Miller maintains a low public profile and rarely seeks the spotlight.

Outside of his business ventures, he remains devoted to co-parenting his two children with ex-wife Caroline Campbell, a celebrated violinist who has performed with renowned artists like Andrea Bocelli, Josh Groban, and Sting.

The former couple married in 2005 and divorced in 2011, but are said to maintain a cordial relationship for the sake of their kids.

While Garner’s life continues to play out in the public eye, Miller seems happy to stay behind the scenes — giving her a steady, drama-free presence away from all the Hollywood noise.
