Kaley Cuoco is celebrating a precious new chapter with her fiancé, Tom Pelphrey, after welcoming their second child together. The 40-year-old The Big Bang Theory star shared the exciting news with her 7.9 million Instagram followers on October 14, 2026, posting nine heartwarming photographs featuring the newborn and her growing family. Alongside the pictures, Kaley revealed that their little girl is named Philomena Carmine Bobby Pelphrey, born on October 12. The actress described the arrival as an incredible blessing, expressing gratitude for the journey that brought them to their daughter. She also shared a loving message for Tom, whom she became engaged to in 2024, calling him her forever partner and celebrating him as a devoted girl dad. The couple already share daughter Matilda, born in 2023, and Kaley made it clear that their family feels complete with the newest arrival. However, the story behind the baby’s distinctive name makes the announcement even more meaningful.

Philomena may be an uncommon choice, but the name carries a beautiful message. With Greek origins, it is associated with meanings such as “lover of strength,” “loved one,” and “courageous lover.” Its vintage charm also reflects the couple’s reported appreciation for classic, traditional names. The baby’s middle names, however, hold an even more personal connection. Carmine is the middle name of Kaley’s father, Gary Carmine Cuoco, and it also appears in the full name of her older daughter, Matilda Carmine Richie Pelphrey. The name Bobby reportedly honors someone on Tom’s side of the family, adding another layer of family history to their daughter’s identity. Following the announcement, fans and fellow celebrities flooded the comments with congratulations, praising the newborn’s name and sharing their excitement for the family. For Kaley and Tom, Philomena’s arrival represents more than another milestone in their relationship; it brings together cherished family connections, a meaningful name, and the joy of watching their two daughters begin life together. As the couple settles into life with their newest addition, their heartfelt announcement has given fans another glimpse into the family moments they treasure most.
