Jennifer Garner Looks Serious After Workout Amid John Miller Engagement Rumors

Jennifer Garner keeps her figure fit and toned through hard work. The actress was recently spotted alone in Los Angeles after putting in some work at the gym.

Garner wore a serious expression after she finished working out on Monday, Feb. 4. In photos obtained by Daily Mail, Ben Affleck's ex-wife wore dark sweatpants, black trainers and a sweatshirt that said Churchill Boxing Club, where she reportedly attended boxing class.

Her ex-husband Affleck was reportedly also spotted getting a cup of coffee in the same neighborhood. The "Justice League" star was seen wearing a New England Patriots hat while getting his drink, showing his loyalty to friend and Patriots' quarterback Tom Brady.

Despite having finalized their divorce last year, Garner and Affleck still live in the same area as they co-parent their three kids: Violet, 13, Seraphina, 10, and Samuel, 6. They tied the knot in 2005 and announced their separation 10 years later in 2015 amid reports that Affleck had been having affair with their children's nanny.

Garner and Affleck still maintain an amicable relationship and were even recently spotted attending church service together with their kids.

Meanwhile, Garner has moved on with John Miller, whom she has been dating for about eight months. And their relationship seems to only be getting stronger, as one source told Us Weekly last month that the two may tie the knot someday soon.

Other sources, however, recently said that Garner and Miller are in no hurry to get married again because they want to take their time in getting to know each other and strengthening their connection.

"[Garner and Miller are] in a true honeymoon phase in their relationship and while they've spoken about a future together, neither of them are ready to plan a wedding or get engaged," an insider told Entertainment Tonight. "Jen has no interest in jumping into marriage quickly. She only just solidified her divorce so right now she just loves all their time together.”

But while Garner and Miller have shown no signs of getting engaged, it seems they have already bonded with each other's children. The ET source said that Miller reportedly always comes over Garner's home to spend time with her and her three children with Affleck.
