Ben Affleck and Jennifer Garner are co-parenting pros.

The former couple, who split in 2015, reunited for the second time this week as they were spotted together at Disneyland for their son Samuel’s 12th birthday.

She remained inconspicuous to the public by pairing the outfit with dark sunglasses.

Affleck, for his part, was more open about his presence in the park as he simply donned a white shirt with a black jacket jeans and colorful Nike dunks for the Saturday outing.

He also clung to a bottle of Diet Coke for his daily dose of caffeine.

The exes — who are also parents to daughters Violet, 18, and Seraphina, 15 — were escorted by multiple members of staff as they walked around the Los Angeles theme park.

They were seemingly accompanied by a nanny, who tagged along with Garner on a ride and stood in line with them at different queues.

Throughout the outing, Garner was photographed holding hands with her youngest child, who looked equally laid black in a gray T-shirt, bright blue pants and black running shoes.

As for the actor, he was snapped walking by himself among the crowd, who seemed unfazed by his presence, while counting the money bills in his hands.

However, for the most part, he remained close to Garner as they chatted amongst themselves.

Earlier in the week, the pair also got together to celebrate their son’s birthday at his school.

The “Good Will Hunting” actor and Garner, both 51, had a seemingly pleasant exchange as they brought treats for Samuel and his classmates.

Affleck, who held his signature Dunkin’ iced coffee, appeared relaxed and cheerful as he talked with his ex-wife, who looked chic in a blazer with thick-framed glasses and a claw clip in her hair.

Despite ending their 13-year marriage in 2018, three years after initially calling it quits, the two have become model co-parents.

After finalizing their divorce, Affleck rekindled his early 2000s romance with Jennifer Lopez and tied the knot in Las Vegas in 2022.

Their blended family also includes the “Let’s Get Loud” singer’s 16-year-old twins, Max and Emme, whom she shares with ex-husband Marc Anthony.

Lopez, 54, told Vogue in 2022 that Garner is “an amazing co-parent,” and noted she and Ben “work really well together” to raise their kids.

The “Jenny From The Block” chart-topper also gushed about her husband’s parenting skills during a 2023 appearance on “The View.”

“Oh, my God. He’s an amazing dad. It brings tears to my eyes,” she said.

“He is honestly the best dad I’ve ever seen.”
