Jennifer Garner fuels engagement rumors with John Miller as she rocks stunning diamond ring during outing

LOS ANGELES, CALIFORNIA: Jennifer Garner has once again set off engagement rumors with her businessman boyfriend John Miller after she was spotted in Los Angeles this week with her left ring finger decorated with an expensive bauble. 

The 52-year-old actress has been spotted wearing a sparkly diamond ring on her ring finger as she was driving through the streets of Hollywood over the weekend, reported Daily Mail. Her sparkly ring was accompanied by another slender gold ring, the outlet mentioned.

However, the sighting has further fueled engagement rumors with her Cali Group CEO beau who she has been dating since 2018.

Jennifer Garner and John Miller are speculated to be engaged

On Saturday, December 21, while Jennifer Garner was driving her car for a solo outing, she was photographed wearing an expensive-looking ring. 

This, in no time, fueled rumors that the ‘13 Going On 30’ actress is taking a step forward in her relationship with her businessman beau. 

The couple have been dating since 2018, briefly splitting in 2020, before getting back together in 2021. 

In October 2024, the ‘Elektra’ actress gave rise to her enagagement speculations when an insider dished that the couple is planning to get hitched in Paris in spring next year. 

Alleging that the actress went to Paris to shop for a bridal gown, the source shared, “Jen and John have taken a lot more trips to Europe than people realize. Paris is one of their favorite escapes and they’ve decided getting married there this coming spring is something they want to do.”

The source further added that the allegedly upcoming nuptials would provide a stark contrast to Garner’s previous marriage to Ben Affleck when the pair eloped to Turks And Caicos in 2005.

The source dished to In Touch Weekly, “This time around she wants a big wedding in a dream location and John is all for it. He loves the idea of giving her something that Ben never did, so he’s totally encouraging her to go all out. He’s got plenty of money and wants to totally spoil her.”

John Miller has ‘really endeared him to Jennifer Garner’, reveals source

The recent speculations of Jennifer Garner taking her relationship with John Miller to the next level came after a source shared with Life & Style that "John has shown incredible patience" with Garner and her ex "and that he’s really endeared him to Jennifer."

Garner was previously married to Ben Affleck and the former couple have maintained a cordial co-parenting relationship for their three children - Violet, 19, Fin, 15, and Samuel, 12.

The source added, "Privately, [John] has been known to find it a little bit intimidating that she’s still so close to Ben, especially when he’s reminded about their red-hot connection back in the day."

"He was exactly what Jen needed at the time,” another source told the outlet, noting, “and he’s been totally loyal to her, but it all comes back to how highly strung and intensely focused she can be about anything she puts her mind to.”
