John Miller was allegedly living with Jennifer Garner part-time before the engagement ring rumors
Jennifer Garner and John Miller first began dating in 2018, not long after her divorce from Ben Affleck was finalized. Miller had also recently ended a marriage. The two likely connected over shared values and a desire for a more grounded, private relationship. Introduced through mutual friends, their bond grew quietly, away from the public eye. Unlike more high-profile romances, Garner and Miller have prioritized keeping things low-key, focusing on family, stability, and a sense of normalcy. Though they briefly split in 2020, they rekindled their relationship in 2021. Since then, they’ve continued to build a steady, drama-free partnership that seems to thrive on mutual respect and emotional maturity.
Miller and Garner haven’t publicly discussed their romance. However, several insiders alleged that the couple planned on tying the knot sooner rather than later. In April 2025, a source told Us Weekly that Miller had already been living with Garner “part-time” after moving out of his Los Angeles house. In August 2025, fans believed they spotted an engagement ring on Garner’s finger.
“He has an office in LA and splits his time between staying there and at Jennifer’s home,” the source noted. “But he’s been staying with Jennifer more often [and] doesn’t want to impose, so he’s looking for his own place … [and] deciding whether he’ll rent or buy.”
Jennifer Garner sparked engagement ring buzz in August 2025
Are John Miller and Jennifer Garner ready to tie the knot? In August 2025, Garner once again ignited engagement rumors when she was spotted in Los Angeles wearing a gleaming ring on the fourth finger of her left hand — a look that caught many eyes and sparked fresh speculation about her relationship with Miller. Photos from DailyMail.com show Garner strolling casually in a blue sweater and jeans as the ring shone brightly on her hand. Previously, in March 2025, insiders spotted Garner and Miller “holding hands and kissing” on a date night, which might prove that the couple’s getting more comfortable with public displays of affection.
This wasn’t the first time Garner’s choice of jewelry ignited curiosity. The delicate band, less flashy than a traditional engagement ring yet notable enough to make headlines, has fans parsing every detail. In October 2024, Garner was also spotted with a ring on that finger. She flaunted a gold ring with a turquoise stone, prompting fans to wonder whether she and Miller were planning to wed.

An insider told Life & Style that Miller made Garner a custom engagement ring that he already gave her in 2022. “John spent a long time making Jen an engagement ring and gave it to her two years ago, around April 2022, which is when she turned 50,” the source alleged.
Could Garner be sporting the alleged secret engagement ring now? Only time will tell.
