Jennifer Garner, 52, and her partner John Miller, 48, are reportedly strengthening their commitment, with Miller increasingly present at Garner's Brentwood residence. This evolving arrangement suggests a growing integration of their lives, with Miller dividing his time between his professional commitments and Garner's home. Speculation regarding an engagement intensified in August 2025 when Garner was photographed wearing a prominent ring on her left hand during a casual outing in Los Angeles. This sighting follows earlier public displays of affection, including instances in March 2025 where they were observed holding hands and sharing a kiss.
John Miller, CEO of CaliGroup, which owns the CaliBurger chain, graduated from Stanford Law School and has a background in business and entrepreneurship, including roles in technology and robotics in the food industry. Garner, an acclaimed actress, also co-founded Once Upon a Farm, a company focused on children's nutrition. The couple, who have been together since 2018 and briefly separated in 2020 before reconnecting in 2021, have maintained a relatively private approach to their romance. Their increased togetherness and recent public appearances have fueled ongoing public interest and speculation about their relationship's progression.
