Jennifer Garner & John Miller’s Relationship Started 5 Years Ago
The Party Down star and her CEO boyfriend have been linked since 2018.
Jennifer Garner has had 20 years worth of TV and movie appearances, including Alias, 13 Going On 30, and Daredevil. Most recently, she joined the third season of Party Down as Hollywood executive Evie Adler.
Offscreen, she’s also found success in her love life. The 50-year-old actor met Ben Affleck in 2000 on the set of Pearl Harbor when Garner was married to Scott Foley, whom she divorced in 2003. In 2004, Affleck and Garner made their first public appearance as a couple. In 2005 they got engaged and married in an intimate four-person wedding. Over the next decade, Garner and Affleck had two daughters, Violet, 17, and Seraphina Rose, 14, and a son Samuel, 10. They announced their divorce to PEOPLE in June 2015 and made it official in April 2017, leaving room for Garner’s new leading man, John Miller, to walk into her life.
Miller is the CEO and Chairman of Cali Group, a tech company founded in 2011 that owns Miso Robotics and several CaliBurger Restaurants. Before that, he graduated from Stanford Law School and was in charge of the “formation, growth and sale” of the pharmaceutical company Arrowhead. Miller has two kids of his own, daughter Violet and son Quest, with his ex-wife and violinist Caroline Campbell.
