Estranged spouses Ben Affleck and Jennifer Garner are taking their insanely cordial relationship across the pond.

The friendly exes are renting a house together in the United Kingdom while the "Batman v. Superman" actor films "Justice League," Us Weekly is reporting.

At the end of the day, it's all about the kids.

A source told the magazine that Jen will be spending April in North London where she will look after the kids — Violet, 10, Seraphina, 7, and Samuel, 4.

A source close to Ben also confirmed the rental arrangement, saying that Ben and Jen are determined to not let their separation affect their children's lives.

"It's what they've always done, married or separated, for the kids," the source said. "Ben is filming 'Justice League,' and they always bring the kids to where they are when they are working. Ben did the same thing when she was filming in Atlanta. They take turns bringing the kids to where the other is on location and just renting a house while they are there."

When they split in June 2015, both parents said they would do anything and everything that was best for their kids, and they've proved it, as they've had several family outings together.

Ben and Jen have been so friendly that many wonder if a reconciliation could be in the future. They've been nothing but complimentary toward each other since the split and they have yet to officially file divorce papers.

"We're doing our very best and we're putting our kids first," he told CBS in late March. "That's how we're focusing on our day-to-day lives, and we don't know what the future's going to hold."

"I am a giant fan of Jennifer," he gushed. "She's just a fabulous person. She's just a wonderful person. She's a great mother. She's a real talent."

Jen discussed her ex at length in February during a bombshell interview with Vanity Fair, calling him the "love of my life."

"I didn't marry the big fat movie star; I married him," she said in the article. "And I would go back and remake that decision. I ran down the beach to him, and I would again. You can't have these three babies and so much of what we had. He's the love of my life. What am I going to do about that?

"He's the most brilliant person in any room, the most charismatic, the most generous. He's just a complicated guy. I always say, 'When his sun shines on you, you feel it.' But when the sun is shining elsewhere, it's cold. He can cast quite a shadow."
