The birth of the pair's first child will be a very happy time, especially since they have both openly spoken about their desire to become parents in the past.

In a 2013 interview with Details magazine, Reynolds said: "We'd love to have a big family. We both come from big families-my parents did four, Blake's did five. A lot of people say it's crazy, but we'll only know when we're there, you know? We'll walk through that fire pretty happily, I think."

Lively echoed these comments during an August 2014 interview with Marie Claire magazine, "I gotta get started. If I could spit out a litter of kids, I would," she said.

The blonde beauty further gushed about wanting to become a mother while speaking with Us Weekly in October. "It's something that I've always wanted ever since I was a little girl," she said. "I knew I wanted to have a lot of kids because I had come from a big family so it was always important to me. So it's just the excitement of that finally being here."

Congratulations!
