Paul also revealed that his Breaking Bad costar Bryan Cranston, 66, has not only met the infant but also has a special relationship with baby Ryden.

"I asked Bryan on his birthday if he would be our baby's godfather," Paul shares, before teasing that Cranston initially turned down the offer.

"No, he's very excited, very honored," Paul continues. "I love the man to death. He's one of my best friends in the world, and, so yeah, it was just a no-brainer."

On Instagram Wednesday, both Paul and Lauren shared the full name of their son: Ryder Casipan Paul.

"My little man. Ryden Caspian Paul. So happy you are out in this world you beautiful boy you. I promise to make you proud little guy. We have been absorbing this baby boy for the last month and feel it's time to finally share the news of his arrival. We love you endlessly," Paul wrote on his page.

Added Lauren in her post, "We've spent the last month getting acquainted with this little guy and we couldn't be more in love. Born on a full moon, he has such a gentle and knowing spirit. I'm so deeply thankful that he chose us to be a part of his journey. Name inspired by our favorite artist, @markryden."
