All About John Miller, Jennifer Garner’s Boyfriend of 4 Years

Jennifer Garner has had an off-again-on-again relationship with John Miller since 2018, but their pairing doesn’t get much attention compared to her ex-husband Ben Affleck’s renewed engagement to Jennifer Lopez. That seems to be how they prefer it. After her divorce from Affleck, Garner seemed to have enough of celebrity relationships and the publicity that comes with them.

A source told US Weekly that Miller is on the same page as Garner explaining, “She loves how little he cares for the limelight or the whole Hollywood scenester stuff… Very different from Ben and J. Lo’s relationship in that way. You’ll never see them ham it up for the cameras or fixate about what events to attend together, it’s just not their style.”

They added, “They’re happier being a regular, under-the-radar couple and don’t need anyone else’s validation to know they’re meant to be together. That’s not to say they’re taking digs against others, it’s just not them.”

Here’s what else we know about their relationship so far.

Who is John Miller and what does he do?

Miller is a businessman who works as the CEO of CaliBurger and its parent company, CaliGroup. From 2004 to 2010, he worked at Arrowhead Pharmaceuticals as the VP of intellectual property and he is also an attorney.

How long after breaking up with Ben Affleck did Garner start dating Miller?

The divorce between Affleck and Garner was finalized in 2018. That same month, a source told US Weekly that the new couple had been together for six months already. She and Affleck had been separated since 2015, and continued to co-parent their three children, Violet, 16, Seraphina, 13, and Samuel, 10.

Miller was still married himself when he and Garner got together. His divorce from Caroline Campbell, with whom he shares two children, was finalized about a month later that same year.

When did Garner and Miller break up?

In August 2020, the couple had a brief split because there were some issues around commitment—from Garner.

“He was ready for marriage and she just couldn’t commit,” said a source at the time. Less than a year later, they got back together and have stayed strong since.

What do their friends think of John Miller and Jennifer Garner as a couple?

Everyone loves these two as a couple.

“Jen’s friends are happy she’s found a nice guy who treats her well,” an insider said. “They trust her judgment and John is certainly a steady and positive influence in her life.”

How is their romance going now?

Since they reunited, it seems like Garner and Miller have worked out any differences and sources close to them say it’s been a wonderful relationship.

“Jen brings out the best in John, and he is the happiest he has probably ever been,” said one insider. “It’s a loving, healthy relationship.”

Another source said, “John is so smitten and caring, but not in an overbearing way… He gives Jen space when she needs it but he’s there for her when the chips are down or she’s in the mood for something spontaneous. They’ve enjoyed some wonderful getaways together … that’s one of their big things.”
