Who Is Jennifer Garner Dating? Meet Boyfriend John Miller

Jennifer Garner is embracing the dating scene! The 13 Going on 30 alum has been romantically involved with her off-and-on boyfriend, John Miller, for nearly three years, having first became a couple in October 2018. Though the pair ended their relationship in 2020, Jen and John have been giving their romance another shot.

“Jen and John are back on,” an insider told Us Weekly in May 2021, noting the Peppermint star and the Cali Group CEO‘s relationship “started up a few weeks” earlier. “They’re on the same page and understand where things stand,” the insider added.

The Miracles from Heaven actress previously dated the American businessman after her divorce from ex-husband Ben Affleck was finalized in 2018, and they were together for more than a year before splitting in August 2020. While it didn’t work out the first time, “John and Jen are in similar places in their lives” now, the source said.

“[They] can relate to raising kids after a divorce,” the insider explained, referring to Jen’s three kids, Violet, Seraphina and Samuel, whom she shares with the Argo actor. John is also a dad of two children with ex-wife Caroline Campbell.

Though the lovebirds tend to keep their off-again, on-again relationship as private as possible, the Pearl Harbor alum revealed the two were going strong when they were spotted out and about in New York City. Jen and her beau were photographed during a rare outing in August 2021.

Despite keeping an extremely tight lip, the Golden Globe winner and the nanomaterials expert have a lot of chemistry. Jen and John may not be ones to flaunt their romance to the public eye, but a source told In Touch in June that the two spend a lot of “private” time together.

When it comes to going on dates, the insider said john will “usually goes to [Jen’s] house or she’ll go to his.” Considering the actress is pretty good in the kitchen, she tends to “[cook] them dinner,” the source added, revealing she’ll whip up “one of her favorite pasta dishes or beef bourguignon.”

While the duo spends the majority of their time indoors, the insider said John and Jen also love getting some fresh air. “[They go] for evening walks on the beach and doing simple things,” the source explained.

It’s no surprise the pair is back together as they were “very much in love” during their first go-around.

“John is the complete opposite of Ben,” a separate source told Us Weekly, noting the Yes Day star prefers dating someone who isn’t in the spotlight. “[Jennifer] loves that he’s not in the entertainment industry and is just a simple guy.”

As for Ben, it seemed the Gone Girl alum wasn’t too happy about his ex-wife’s budding relationship. Though Ben and Jen split after 10 years of marriage in 2015, with their divorce being finalized three years later, In Touch reported the Hollywood hunk wasn’t John’s biggest fan.

“Ben is used to his ex-wife dropping everything for him, but that’s all changed and he’s no longer at the top of her list of priorities,” an insider told In Touch in December 2018. “He winces whenever Jen brings up John’s name. He can’t help finding faults with him, even though John’s the nicest guy and hasn’t done anything wrong.”

Now that Ben has rekindled his romance with former fiancé Jennifer Lopez, perhaps his tune has changed.
