The couple, who have been married ten years, welcomed daughter Charlotte Easton in 2013.
Cook, 35, and Gillies, 38, admitted the pregnancy was a bit of a surprise, but they are thrilled.
The couple confirmed the pregnancy to E! New, stating, “We’re as happy as we were surprised by this wonderful news! We haven’t slept since 2013 and welcome advice from all parents who survived Two Under Two.”
Spider Man 2 star Gillies tweeted when Rachael gave birth to Charlotte, “It’s a girl. the tiny new empress of my everything. she’s immaculate. we’re delirious”.
Daniel gushed over his daughter more in March, saying, “She’s the greatest thing ever. I don’t know what to say. I get to see her about one day a week because of the show. I fly home every single weekend to see her, and she’s heaven. I can’t describe what it’s like to look at her, to hold her. She’s just a happy, beautiful kid. Honestly, any guy who’s lucky enough to have a daughter is a king.”
His show now films in Atlanta, Georgia.
