A source told OK! magazine that Miller proposed to the actress soon after her 50th birthday in April 2022.

According to the insider, Jen and John's preparations have nothing to do with Ben and J.Lo's wedding.

They said, "It was simply a matter of when John would propose and how long they would postpone making it official.

Are John Miller and Jennifer Garner engaged?

Garner and Miller initially ignited engagement rumours back in November 2021, yet nothing has yet been confirmed.

The "13 Going on 30" actress participated in an Instagram live conversation with Judy Greer to discuss "the benefits and drawbacks of being sober-ish."

Viewers immediately saw a gold ring with pearl accents on Garner's left finger when she first appeared in the video cradling a mug of tea between her palms.
