Last came a photo of all the tissues Cuoco had cried through during the table read. "Prepare yourselves ... for a finale that has truly given me a loss for words ❤️ Our whole universe .... @bigbangtheory_cbs," she captioned the snap, as her Big Bang Theory co-stars also shared pics from the memorable day.
Cuoco, who has starred as Penny on Big Bang since its first season 12 years ago, told ET in January that she was expecting a lot of tears during the show's finale.
"I was laughing. I was like, 'How are we gonna shoot the last episode?'" she recalled. "I was hoping we were gonna pre-shoot a lot of it 'cause I think there are gonna be a lot of tears."
"It’s gonna be tough, it’s gonna be a lot of emotions and I love our crew. I just love the people that we’re with every day so, you know, all good things come to an end," Cuoco added. "Everyone is still madly in love with each other. We're all OK with the choice. We’ve just grown up together, so it’s our adult decision."
