Jennifer Garner keeps her personal life private, focusing on her children Violet, Fin, and Samuel in Los Angeles. Since 2018, she has been in an on-and-off relationship with CaliBurger CEO John Miller, though they avoid discussing their relationship publicly.

Engagement rumors surfaced in 2021 when Jennifer was seen with a gold ring on her left hand. After a brief split, the couple reunited in 2022, reigniting speculation when she wore a gold band with turquoise and green stones.

Sources describe the couple as compatible and enjoying low-key activities together, often avoiding the spotlight. However, neither has addressed the engagement rumors.
