Kaley Cuoco attends the Los Angeles Season 2 Premiere Of HBO Max Original Series "The Flight Attendant" at Pacific Design Center on April 12, 2022 in West Hollywood, California.

During an April 28 visit to The Kelly Clarkson Show, Kaley Cuoco showed a vulnerable side to her as her voice shook while discussing her recent Glamour cover story. She discussed, in part, details the physical and emotional turmoil she dealt with following her divorce from husband Karl Cook.

“I’m very open. I’m very happy and life is normally pretty good and I don’t like complaining because I have so much to be grateful for,” The Flight Attendant star told Kelly Clarkson. “I wanted to be very upfront that it wasn’t my best year. And I’ve been very sad.”

In September, Kaley and Karl announced that they had ended their relationship after more than three years of marriage. In a joint statement to E! News, they shared, “Despite a deep love and respect for one another, we have realized that our current paths have taken us in opposite directions.”

“I think social media is very wonderful for so many reasons but it shows just ALL the good stuff,” Kaley said on the show. “It makes you feel kinda crappy when you look at someone else’s life and you think they have it all.”

Kaley also took a moment to credit her Flight Attendant co-star and “best friend” Zosia Mamet for her incredible support while they filmed Season 2 of the popular HBO Max thriller-comedy show together. “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 somedays without her,” Kaley explained. “I never thought I had to depend on anyone like that before and I really depended on her. She helped me through so much.”

The actress began to get teary-eyed as she recounted how Zosia would often show up to set—even on her days off—to have lunch with her because she was having “a rough time.”

“She’s the best,” Kaley shared. “I’m very lucky that I had her.”
