Kaley Cuoco Tears Up In Instagram Photo Before 'Big Bang Theory' Finale

"Big Bang Theory" star Kaley Cuoco has tears in her eyes in her latest Instagram post, and no, it's not because of the upcoming Season 12 finale.

In her Instagram page, Cuoco posted a sweet photo of herself and husband Karl Cook with two of their pals. According to Cuoco's caption, her two pals had gotten engaged, with one of them even showing off her new engagement ring.

In the photo, Cook made a funny face at the camera. His wife, on the other hand, seemed to have gotten emotional after hearing the news as she had tears in her eyes. Cuoco also wrote in the caption that she would be joining in on the wedding planning for her friends' big day.

Perhaps, Cuoco will be sharing some wedding tips to her friend from her own ceremony just seven months ago. The "Big Bang Theory" star tied the knot with the professional equestrian on June 30 last year at an intimate wedding at a horse stable near San Diego, California. Cuoco and Cook only invited close pals and family to their nuptials.

Following the ceremony, Cuoco shared the happy news to her Instagram followers with a sweet photo. She posted a snap of her and Cook kissing at a horse stable, along with the message: “Legally KCSQUARED 6-30-18.”

For her wedding, Cuoco wore a gorgeous white lace dress with a cape from Reem Acra, while her husband looked dapper in a tuxedo. After the ceremony, however, the actress changed into a lace Tadashi Shoji jumpsuit and Louise et Cie shoes for the reception that followed.

After dating for almost two years, Cook popped the big question to Cuoco on the latter's birthday in November 2017.

In March 2018, Cuoco opened up about her then-fiance and why she believes they are "perfect" for each other.

"[Karl] lets me wake up in the morning and say, 'I want to go and rescue rabbits.' And he's like, 'All right, let's get a coffee and let's go.' And that is him. We are the same, our views are the same, our morals are the same, he is my perfect match," she told People.

Meanwhile, Cuoco's long-running CBS series "The Big Bang Theory" will end after Season 12.
