The Flight Attendant star said her HBO costar Zosia Mamet was a pillar of strength for her during her divorce from ex Karl Cook. In a conversation on The Kelly Clarkson Show, Cuoco, 36, opened up about how Mamet went above and beyond to help the actress while filming season 2 of the series. "She basically lived with me the last few months of shooting, we just moved in together, and I don't think I would've gotten to work some days without her," Cuoco said. "I never thought I had to depend on anyone like that before and I really depended on her. She helped me through so much."

"I'm like 'You have your day off today' and she's like 'I'm coming in,' cause she heard I was having a rough time, and she would sit in my trailer." "She's the best," she said of Mamet.
