Jennifer Garner Photographed Enjoying Holiday With Her Kids Sans Boyfriend John Miller

Jennifer Garner may have spent Valentine's with boyfriend John Miller, but she devoted her weekend to her kids and friends.

The "Love, Simon" actress, 43, was photographed with Seraphina, 10, and Samuel, 6, the younger two of the three kids she shares with ex-husband Ben Affleck. They were in Bozeman, Montana, not far from Yellowstone National Park. In photos shared by Daily Mail, Garner and her two younger children were in the company of their family and friends during their holiday.

Photos from the outing showed Garner going for comfort with her ensemble, wearing a flannel top, black sweater, torn jeans and boots. She accessorized with a pair of dark sunglasses.

Her boyfriend, Miller, wasn't spotted with them, but he and Garner did enjoy a breakfast date and packed on some major PDA the day before Valentine's.

The couple grabbed a meal at the Farmshop restaurant in Brentwood Country Mart mall in LA on Feb. 13. Before they left to go about their day, Garner and Miller shared a warm hug and exchanged some sweet nothings before leaving in separate cars.

The couple's relationship has only been getting more serious, but a source recently told Entertainment Tonight that they are still in the honeymoon phase and aren't planning on taking things to the next level at the moment. Garner, who finalized her divorce from Affleck in October last year, reportedly isn't ready to jump into another marriage so soon.

"[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," the insider said.

And while he wasn't spotted with them on their Montana holiday, it seems Miller would have enjoyed it as the source said he has a love for the outdoors. Miller reportedly also shares a lot of Garner's interests, including eating healthy.

"Jen has something very different with John than she had with Ben," the source revealed. "She and John are both interested in living a healthy lifestyle, working out and eating well, except for the occasional trip to Chick-fil-A!"

"They've already taken the kids to the mountains together, and Jen's friends describe John as a mountain man," the source added.
