Ben Affleck was all smiles while reuniting with his ex-wife, Jennifer Garner, and their three kids in Florence, Italy on Thursday.

The “Argo” actor, who arrived on a private jet, was photographed walking across the tarmac with his arms spread wide open as his 11-year-old son, Samuel, ran to meet him.

The father and son shared a sweet embrace before Affleck was greeted by his older children — Violet, 17, and Seraphina, 14.

The 50-year-old, who wore tan pants and a navy button-up, appeared overjoyed to reconcile with his kids after spending time in Southampton, N.Y. with wife Jennifer Lopez.

Affleck arrived in Italy on a private jet Thursday.

The actor was immediately greeted by his son, Samuel.

The father-son duo shared a sweet embrace.

The surprisingly chipper actor eventually made his way over to Garner, who was in equally good spirits.

The pair, who were married from 2005 to 2018, seemed to have an impassioned conversation for nearly half an hour before hugging one another goodbye.

The Oscar winner left with their three kids as Garner, 51, went on her own to do a little window shopping.

He then went over to greet Garner.

Both Affleck and Garner seemed to be in great spirits.

The exes had an animated conversation.

The family of five chatted for about 30 minutes before going their separate ways.

The “13 Going on 30” actress, who looked casual in a striped shirt, was photographed inside a bookstore before grabbing a bite to eat.

While it’s unclear how long Garner had been in Europe without Affleck, the mother of three was spotted in Malibu with her kids last week.

The foursome was photographed enjoying brunch at Soho House on July 23 — the same weekend that Affleck threw Lopez an over-the-top birthday party in their new $60 million Beverly Hills mansion.

The “13 Going on 30” actress wore a striped shirt and jeans.

Affleck and Garner were married from 2005 until 2018.

The kids said their goodbyes to Garner before leaving with Affleck.

In fact, the “On the Floor” songstress revealed earlier this week that Affleck’s three children, as well as her own kids, were all in attendance for the birthday bash.

“All the kids were there, it was a gorgeous day full of sunshine and perfect for a pool party!!” she wrote in the July 31 edition of her “On The JLo” newsletter.

The lavish gathering featured massive bouquets of pink flowers, overflowing charcuterie boards and lots of dancing — including on tables.

The three kids eventually left with their dad, leaving Garner to explore the city on her own.

The actress browsed a couple of nearby shops after separating from her kids.

She also sat down at a restaurant to grab a bite to eat.

Lopez — who shares 15-year-old twins, Max and Emme, with ex Marc Anthony — and Affleck have put a lot of effort into blending their families, which hasn’t been easy with so many teenagers under one roof.

“They’re becoming adults. They are challenging everything in life. They’re looking at everything,” the “Mother” star said on the “Today” show in April.

However, she thinks that their rebellious attitudes might be “great for our world.”

“I think they’re going to change the world, to be quite honest — oh, and make it so much better, so much better than what we did.”
