Zosia Mamet and Kaley Cuoco

Kaley CuocoandZosia Mamet’s friendship istoocute for words.

Over the weekend, theBig Bang Theoryalumshared a videoof the pair watching themselves inThe Flight Attendant’s second season finale, which aired last Thursday. Both Cuoco, 36, and Mamet, 34, teared up seeing their characters' onscreen friendship — even squealing, at one point.

“Are you crying?” Cuoco asked as Mamet replied, “I’m crying!”

“Me too,” Cuoco added.

Copying their characters in the scene they had just viewed, the duo adorably tapped each other’s noses.

Cuoco and Mamet play best friends Cassie Bowden and Annie Mouradian on the acclaimed HBO Max dramedy. While working on the series, the two actresses were able to develop a close bond offscreen as well.

Recently, Cuoco revealed that theGirlsalumhelped her through her divorcefromKarl Cook.

“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 onTheKelly ClarksonShowin April. “I never thought I had to depend on anyone like that before and I really depended on her. She helped me through so much.”

Cuoco also shared how Mamet visited set on days she wasn’t even scheduled to shoot just to support her castmate.

“She would come to work on days she didn’t have to be there and come and have lunch with me,” she continued. “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.”

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