The 55-year-old 'Seduced and Abandoned' star's wife Hilaria Thomas, 29, is expecting a baby girl in three months time and is trying to get over her fear before then.
The yoga instructor and 'Extra' correspondent told People.com: "Now I have to start thinking about giving birth. I haven't thought about that before. I saw a birthing video the other day and I cried. Hopefully I will survive. I just have to remember that a lot of people have babies, it's a unique experience and I will be okay."
Meanwhile, Hilaria revealed that her husband keeps stealing her pregnancy pillow and used it to help him get his beauty sleep while promoting his new movie at the Cannes Film Festival this week.
She said: "Since I'm pregnant I brought my pregnancy pillow, it's called a Snoogle. So I was walking with my carry-on and this huge pillow that I had many questions in the airport what it was.
"My husband stole my Snoogle. I kid you not, I woke up and stole it back from him, but we woke up refreshed this morning and we're ready to go."
The brunette beauty insisted that the former '30 Rock' star has been very supportive during her pregnancy.
She said: "Alec is fantastic. Alec is a really great partner. We're always believe that we're on the same side, and he takes care of me, so getting me any food that I want at any hour of the night."
