"She said, 'First thing you need to know is never say the word relax and don't ever say breathe.' She said that my wife would most likely hit me if I do. So, I'm like, 'OK, that's good to know,'" Paul said.

He continued, "She's just telling me what not to do. She goes, 'Just prepare yourself. I've helped deliver over 600 babies and 100 percent the mother of the baby who's delivering absolutely hates her partner."

Paul and Lauren announced the pregnancy in September and revealed the baby's gender in November.

Paul is best known for his Emmy-winning performance as Jesse Pinkman on AMC's Breaking Bad. He now stars on Hulu's The Path.
