The couple's only daughter, Matilda, was born on 30 March, 2023. Cuoco announced the news on Instagram, writing, "Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives! We are overjoyed and grateful for this little miracle 💓 Thank you to the doctors , nurses , family and friends who have helped us immensely over the last few days. We are blessed beyond belief 💗 @tommypelphrey didn't think I could fall even more in love with you , but I did 💗."
Similarly, Pelphrey wrote in part on a separate Instagram post, "My heart is full of love and gratitude for this miracle…."
Given that Matilda is only a few months old, the couple are mainly focussed on surrounding her with love and enjoying the early, special moments of parenthood.
