It鈥檚 an exciting start to the holidays for Kaley Cuoco! The Big Bang Theory star revealed that she is engaged to boyfriend Karl Cook, and her reaction to the proposal was so emotional 鈥 and also totally adorable.

In an Instagram video posted to both of their accounts, Cuoco can鈥檛 contain her tears, and Cook can be heard asking, 鈥淲hat鈥檚 on your finger, hon?鈥 She shows a beautiful diamond ring and squeaks out an excited, 鈥淲e鈥檙e engaged!鈥 before starting to bawl again. Cook reminds his now-fianc茅e that she still hasn鈥檛 officially said yes, so she rectifies it immediately by saying 鈥淵es!鈥 repeatedly while cry-laughing.

鈥淪till crying,鈥 wrote Cuoco. 鈥淓very part of this night has been perfection just like you @mrtankcook. I love you forever!鈥

Just hours before the proposal, Cook, a professional equestrian, posted a photo of himself holding up a giant novelty diamond ring in Target while Cuoco looked on, unimpressed. Shortly after, he posted the real deal. 鈥淲ho knew my prior post was oracular?鈥 he wrote. 鈥淎fter nearly two years I finally got up the courage to ask her to marry me. This is the best night of my life and I think the video shows it is the best night for Kaley as well鈥..of [course] she said yes!!鈥

Cook also shared a close-up of the gorgeous pear-shaped diamond ring he gave his bride-to-be.

The celebrations for the pair continued into the night, as they danced to Ed Sheeran鈥檚 romantic ballad 鈥淧erfect鈥 and showered each other with affection. 鈥淎ll I want is to be a balloon bouncing, bobbing, and flowing through life together,鈥 Cook wrote to his new fianc茅e. 鈥淵ou are my everything.鈥

The happy couple started dating in spring 2016, just a few months after Cuoco split from her ex-husband Ryan Sweeting in late 2015. Earlier this year, Cuoco teased fans about engagement rumors between the two lovebirds 鈥 and now, they鈥檝e come true. Congrats to the happy couple!
