While the media has spent years spotlighting Ben Affleck’s rekindled romance and marriage to superstar Jennifer Lopez, his ex-wife Jennifer Garner has been quietly living a love story of her own—one far from red carpets and flashing cameras. Garner, 51, has been in a low-key, on-and-off relationship with businessman John Miller, a man who prefers life well outside the Hollywood bubble. And although their romance began away from the public eye, it’s grown into something meaningful, steady, and refreshingly private.

Garner and Miller reportedly began dating about six months before her divorce from Ben Affleck was officially finalized in 2018. Since then, they’ve chosen to keep their relationship largely under the radar, prioritizing privacy and emotional connection over public displays. Their story couldn’t be more different from the headline-grabbing Affleck-Lopez reunion, which led to a glamorous Vegas wedding and a music video serenade in J.Lo’s song “Can’t Get Enough.”

So who exactly is the man who’s won Jennifer Garner’s heart? John Miller is a 1978-born entrepreneur and attorney who serves as the CEO of CaliGroup, the parent company behind CaliBurger, a growing fast-food chain. Before that, he held a leadership position at Arrowhead Pharmaceuticals as vice president of intellectual property. He was previously married to violinist Caroline Campbell, with whom he shares two children: a daughter named Violet and a son named Quest.

Miller’s life has remained largely out of the spotlight, and that seems to be exactly how both he and Garner like it. According to sources close to the couple, this shared value of privacy is a key part of their strong bond. “She loves how unaffected he is by the limelight and the whole Hollywood scene,” one insider told Us Weekly. “They don’t dress up for the cameras or obsess over public appearances—they’re just a regular couple who enjoy being together.”

Their decision to step back from the public eye hasn’t stopped fans from being curious—especially after Affleck’s highly publicized wedding to Lopez in July 2022. However, any speculation about Garner’s emotional state was quickly quieted when she and Miller were spotted together shortly after, smiling and enjoying each other’s company in candid paparazzi shots. In fact, one telling moment came in January 2023, when Entertainment Tonight reported that Affleck was seen chatting happily with Miller outside Garner’s home, proving that exes can truly get along—and that Garner’s relationship is fully embraced by those closest to her.

Though their journey hasn’t been without pause—the couple took a break from August 2020 to spring 2021 due to differing timelines around marriage—they’ve since found a rhythm that works for both of them. At the time, sources said Miller was ready to take the next step, but Garner wasn’t quite there. Since then, however, they’ve grown closer, even reaching milestones such as inviting Garner’s family to a food drive for her 50th birthday. While they’re not rushing to blend families or race to the altar, they’re deeply committed to each other.

Garner, who shares three children with Affleck—Violet, now 17; Seraphina, 14; and Samuel, 10—has made it clear that her relationship with Miller is something she deeply values but wants to protect from outside pressure. A source close to her said, “She’s not as shy as she used to be. She and John are much more comfortable and confident with each other now, and she enjoys showing that off a bit more.”

The couple is often spotted doing everyday things together, like shopping in Montecito or going for early morning runs. They show their affection quietly—through hugs, shared smiles, and simply being present for one another. And while they may not be making headlines like some of Hollywood’s power couples, those close to them say the connection is deeply special.

“They have a mutually supportive relationship that brings out the best in both of them,” a friend shared. “John is kind, caring, and always respectful of Jen’s space and independence. He stands by her without ever overshadowing her.”

Another source added that Miller is content letting Garner take the lead. “He’s happy to go with the flow,” they said, “and that’s exactly what Jen needs right now. There’s no pressure, just love, and support.”

Jennifer Garner has spent much of her adult life in the spotlight, especially during her high-profile marriage and divorce. But in John Miller, she seems to have found a safe, loving space where she can just be herself. And while they may not crave attention, their bond is proof that sometimes, the most powerful relationships are the ones that quietly flourish away from the public eye.
