\"Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives! We are overjoyed and grateful for this little miracle,\" Cuoco wrote on Instagram at the time, alongside a photo of the newborn. \"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,\" she added.

Cuoco has since shared glimpses of Matilda on her social media platform to celebrate various occasions, including Easter and Father's Day.

Matilda is the couple's first child together.
