The couple have been very vocal about their excitement over the start of their family.

According to Us magazine, Romijn referred to having babies as a dream.

“I was never a girl who dreamed about what her wedding day would be like, but I’ve always dreamed about decorating my baby’s nursery.”

She added that she was confident her husband would make a “fantastic dad.”

“He’s a pragmatic, smart, savvy, enthusiastic person. He really lives his life with tremendous integrity, and he’s a healthy person in every single way.”

O’Connell, for his part, joked that he only wants his girls to date “men who run countries.”

Indeed, the couple has had quite a sense of humor throughout the pregnancy, with Romijn joking in November that she was a “beached whale.”

O'Connell stars in the new Fox sitcom "Do Not Disturb."
