Who Is Jennifer Garner's Boyfriend, John Miller? All About His Job, Ex-Wife & Kids
Jennifer Garner‘s boyfriend John Miller stays out of the public eye and is certainly not the actress’s most well-known romance but we have gotten some insights into their low-key relationship over the years.
Garner and Miller started dating in 2018 and have been together (almost) ever since. Their relationship began shortly after Garner finalized her divorce from ex-husband Ben Affleck from whom she separated in 2015. Affleck and Garner share three children, Violet, Seraphina and Samuel.
In a rare update, sources told People on Dec. 6 that the 13 Going On 30 actress is “very happy with” Miller “spends a lot of time with him.”
Still though, you might be wanting to know more about Garner’s boyfriend and their ultra-private relationship. We’ve got you covered.
Who Is John Miller?
John Miller is the founder and Chairmain Cali Group, a California tech company that owns restaurant chain Caliburger. Miller is CEO of its portfolio company, PopID.
Miller Founded Cali Group in 2011
Miller founded Cali Group in 2011 after previously working at Arrowhead Pharmaceuticals as the VP of intellectual property. Cali Group started out as a singular restaurant before Miller and his team built out the company.
“We really think of ourselves as a technology company that happens to sell cheeseburgers,” Miller said in 2017. He opened up further about his company’s start while speaking at RestaurantSpaces in 2020, saying that, at first, “I had no idea what I was doing.”
“I realized in about a year that this is the hardest business in the world.” After putting a lot of money in and having failure after failure, I decided to focus on building technology for our restaurants,” he added.
Miller Is Also an Author & Attorney
Miller is a Stanford Law graduate and went on to join the California Bar in the Northern District of California. In 2004, he co-authored The Handbook of Nanotechnology Business, Policy and Intellectual Property Law in 2004, which analyzes the legal and commercial challenges of nanotechnology.
He has also written articles on legal and policy issues in the nanotechnology and served as a managing editor of Nanotechnology Law & Business.
Miller Is a Father of Two & Was Previously Married
Miller shares two children, a son and a daughter, with ex-wife Caroline Campbell, a violinist who has performed with Andrea Bocelli, Josh Groban and Sting. Miller and Campbell’s son was born in 2006 and their daughter, Violet, was born in 2008.
Miller and Campbell married in 2005 and divorced in 2011 but, per Us Weekly, reconciled in 2012 before refiling for divorce in 2014. Per The Blast, Campbell accused Miller of having “anger” and “control” issues in a 2016 court filing over the custody of their children. “I believe he feels satisfaction from controlling me and making me pay the price for ending the marriage,” Campbell said in a statement while agreeing to 50/50 custody. “To avoid scenes, minimize the stress on the children, and protect their happy home environment, I usually opt to go along rather than risk John’s anger.”
Their divorce was finalized in 2018.
Garner & Miller Started Dating in 2018
On Oct. 24, 2018, Us Weekly reported that Miller and Garner had been dating for six months. People also confirmed that Garner and Miller were “casually dating but it’s not serious.” Garner finalized her divorce with Affleck earlier that month. The following month, the couple were spotted together for the first time outside an LA theatre after seeing the musical Dear Evan Hansen.
People reported that the couple were still not serious. “She doesn’t call him her boyfriend,” the source said. “But she loves getting attention from John. They have fun together and it’s easy.” The source added: “She only sees John when she isn’t busy with her kids. He understands that her kids are her number one priority.”
Miller and Garner split in early 2020. “I definitely don’t think that I’ll be single forever,” Garner later told People in March 2021, confirming her relationship status. “But this is not the time. I don’t need to complicate it; I’m good.” However, in August 2021, the couple were seen together again, signaling that they were back together.
They Appear To Be Close With Each Other’s Children
In 2022, Us Weekly reported that Miller’s kids and Garner’s kids had met for the first time and that it was “casual and easy.”
In 2023, Miller’s daughter, who shares a name with Garner’s oldest daughter, had a small role as a teenage violinist in Netflix’s A Family Switch, which Garner produced and starred in. “Jennifer thought it was a great idea. Violet even auditioned,” a source told Us Weekly. “John is definitely encouraging his daughter to go into acting because Jennifer loves it so much. Her artistic influence is really strong.”
Miller even seems to get along with Garner’s ex-husband. In January 2023, Miller and Affleck were photographed laughing together outside Garner’s home. “Ben is super down-to-earth, and so is John. They have a mutual respect for each other and are always very friendly with one another,” a source told Us Weekly in November 2023.
Do Miller & Garner Plan To Get Married?
In October, sources claimed Miller and Garner are moving towards getting married. A source told In Touch that the pair are planning a “dream ceremony in Paris.”
However, back in January 2023, a source told Us Weekly the pair were in no rush down in aisle. “Jennifer adores John and still sees a long-term future with him. There’s no desire on her part to slow things down, spend less time together or anything like that,” a source told the outlet. “She’s just decided after a lot of thought that she’s just not in a hurry to rush down the aisle just yet and that she feels perfectly happy cherishing and enjoying what they have—for now—without a formal label.”
