“We’re engaged!” she tells the camera through tears.

Cook responds, "You still haven't said yes yet," and she immediately answers, "Yes! I say yes! I say yes!" Following the big proposal, Cook shared an up-close look at the sparkler that's now on Cuoco's finger.

Cook, the son of Intuit co-founder Scott Cook, also shared sweet sentiments with his new fiancee with a sweet video of their post-engagement dance.

"In life, there is nothing like dancing right after getting engaged. The purity and grace of the moment are inexplicable, it is truly as though life were a balloon bouncing on the smoothest zephyr. Honey, all I want is to be a balloon bouncing, bobbing, and flowing through life together. You are my everything @normancook," he wrote.

The couple started dating in 2016 after making their first red carpet appearance in September of that year. Cuoco was previously married to former tennis player Ryan Sweeting from 2013-2016.
