Celebrity Parents Christina Ricci Says Husband Mark Hampton Chose Baby Cleo's Full Name Without Telling Her The Addams Family actress gave birth to the couple's first child in December By Abigail Adams Abigail Adams Instagram Twitter Digital News Writer, PEOPLE People Editorial Guidelines Published on January 13, 2022 11:09 AM Share Tweet Pin Email Cleopatra it is! In a sneak peek of Thursday's episode of The Ellen DeGeneres Show, Christina Ricci revealed that she and her husband Mark Hampton miscommunicated when naming their now-1-month-old daughter. According to the actress, 41, the discussion began as she prepared to deliver her baby via cesarean section on Dec. 8, when the topic of the birth certificate came up. At the time, Ricci said, the couple had simply landed on calling their newborn daughter Cleo, but nothing more. "My husband was like, 'Well, we're going to give her a full name right? And the nickname is Cleo?' And I was like, 'Cleopatra?' And he was like, 'Yeah, the full name's Cleopatra.' And I was sort of like, 'Fine, whatever. We'll talk about this later,' " she recalled. After giving birth, however, Ricci realized she and Hampton weren't exactly on the same page. "He got so excited he put it on Instagram, and media outlets picked up that her name was Cleopatra Ricci Hampton, and I was like, 'Oh, I guess her name's Cleopatra,'" she told host Ellen DeGeneres.
