Carrie Coon, the talented actress behind Bertha Russell on HBO's The Gilded Age, has revealed that her co-star Morgan Spector's 7-year-old daughter is a budding star in her own right. According to Coon, the young girl has mastered an impressive impersonation of her character, Bertha Russell.

In an exclusive interview with PEOPLE, Coon and Spector opened up about their experiences bringing their young children to the set of The Gilded Age. Coon, who has a 7-year-old son and 4-year-old daughter with husband Tracey Letts, revealed that her kids find it "disconcerting" to see her in character, especially with the extensive makeup and wig required for her role.

Spector, on the other hand, shared a heartwarming story about his daughter's visit to the set in Rhode Island. "I brought my daughter to the set in Newport so she could see the mansions, which I think are fantastic," he recalled. "The costume department immediately saw her, grabbed her, took her into a trailer and somebody did some magic and turned her into a princess. They gave her one of Bertha's tiaras and she was overjoyed."

Coon and Spector both agreed that having their kids visit the set can be a wonderful experience, but it's not always easy. "It's great to bring kids to set and I've always found that the crew is always really lovely and generous about it," Coon said. Spector added, "Everyone has kids that they're not getting to see. So they're starved to see a child."
