Meet Nate Berkus and Jeremiah Brent's Baby Boy, Oskar!

Interior designers Nate Berkus and Jeremiah Brent welcomed their second child, a son, via surrogate on March 26 in Los Angeles. And the couple chose a surprising namesake for their baby boy: Berkus’ former partner Fernando Bengoechea, who died tragically in the 2004 Sri Lankan tsunami. “His middle name was Oskar,” Berkus, 46, tells PEOPLE exclusively of the poignant inspiration — and what’s more surprising, the tribute “was actually Jeremiah’s idea.” “We have always honored Fernando’s memory in our relationship. He’s a part of our love story,” explains Brent, 33. “It’s such an important chapter in Nate’s life. So the idea that we can honor his memory in a beautiful way was exciting to us.” Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?

The kids will know both of our stories, where their names came from, and why.” For now, what Brent refers to as their “little tribe” of four is soaking in the present. “We’re so grateful every second of the day just to have them both,” he says.
