"I'm a proud dad: my son gave Zaddy side eye, unprovoked," Cohen captioned a photo of Ben looking at his Uncle Anderson in April 2019.

Cooper welcomed his son, Wyatt Morgan, via surrogate on April 27, 2020.

Cohen celebrated on Instagram, posting a photo of the pair and captioning it, "'new life, new hope!'" He added, "Wyatt Cooper, you couldn't have come at a better time! I know a friend who can't wait to meet you! ♥️"

On Father's Day 2020, the pals celebrated by introducing their sons for the first time virtually, on Cohen's episode of Watch What Happens Live.

Cohen told his son during the broadcast, "Ben, this is Wyatt. This is Wyatt Cooper. He's gonna be your good buddy." The Bravo star continued, "That's gonna be your good buddy and we're gonna travel together. And if you like him half as much as I like his daddy, you're gonna be great friends."

We're not crying, you're crying!

In October 2020, the pair had a playdate at the playground, snapping a selfie to commemorate the moment.

Cohen said on his radio show in May 2020 that he was "so happy" for his close friend, adding, "We've been talking about this for a long time and I have been really enjoying Anderson coming over."

He continued, "His visits with Ben have taken on a special significance since we both knew for a while that Anderson was planning on [becoming a dad] himself."

Cohen added of his friend, "He went through a lot, and I'm just so happy that his son is so beautiful and happy and healthy.

"I've already seen Anderson light up and open up in new ways. Like all homes that welcome a baby, his home is now full of the music of new life and family."

Cooper kept busy with Ben in September 2020, with Cohen sharing that "Ben sweeps while Anderson reads" for their "morning activities."

On Live with Kelly and Ryan in October 2020, Cooper said that the boys had just finally met in a much-delayed get-together given the COVID-10 pandemic.

"They met for the first time a couple weeks ago, up in Connecticut. It was cool," Cooper revealed.

While he's not sure "if Wyatt even understands who [Ben] is," Cooper added that his son was "sort of fascinated" by Cohen's son anyway.

"And Benjamin was very sweet with him," recalled Cooper. "He kept poking him."
