Designer Nate Berkus and husband Jeremiah Brent on Monday welcomed a baby girl into their family.

Poppy Brent-Berkus was born via surrogate.

“Jeremiah & I are thrilled to announce the arrival of our daughter, Poppy Brent-Berkus, born via surrogate on March 23, 2015,” Berkus wrote in a Facebook post. “We are so excited to finally be a family of 3.”

“As anyone with a newborn knows, we have our work cut out for us but couldn't be happier to be embarking on this life changing journey that is parenthood. Thank you all for your well wishes and support,” he added.

The men made history in May as the first gay couple to marry at the iconic New York Public Library, roughly a year after Berkus proposed atop the 15th-century Inca site Machu Picchu in Peru.

Berkus, 43, currently hosts the NBC reality show American Dream Builders, while Brent, 29, is a designer who appeared on cabler Bravo's The Rachel Zoe Project.
