Nate Berkus and Jeremiah Brent have welcomed their second son together, via a surrogate.

The Nate & Jeremiah By Design co-stars shared that their new bundle of joy Oskar was born on Monday, March 26th. They used social media to announce the fabulous news their family had welcomed a new addition.

“It is with so much love that we welcome Oskar Brent-Berkus to our family. We have waited for you, we already love you, and we as a family stand on the shoulders of so many people who have made it possible for families like ours to continue to grow.- Nate, @JeremiahBrent and Poppy,” tweeted Berkus along with a black and white picture of their newborn son’s foot.

Soon Brent also took to social media to share his own message, as he too gushed about his baby boy.

“Yesterday, life cracked open in a way I didn’t think it could again with the birth of our son Oskar Brent-Berkus, Love multiplied. How can love continue to expand like this. Hand in hand our family is basking in the phenomenon of it all. We love you little Oskar. How thankful we are. How beautiful it all is,” shared Brent in an Instagram post.

If it seems like the couple just announced they were expecting their second child, it's true! It was only in February they revealed their big news. Berkus and Brent used their adorable 3-year-old daughter Poppy to share their little family was expanding. They did not give out any information regarding their surrogate, including whether or not it was the same surrogate they used when Poppy was born in 2015.

As for how the little girl feels about having a baby brother, Brent recently told Entertainment Tonight she was getting her big sister pants on. Not sure what that means, but it sounds like she is as ready as any toddler could be for a sibling.

The hit TLC stars of Nate & Jeremiah By Design began dating in 2012. They wed at the New York Public Library in 2014. Four years later, they are now living the dream with a beautiful daughter and son. Plus, being on a hit TV show doesn’t hurt either.
