Cuoco and Cook have been dating for almost two years. "This is the best night of my life and I think the video shows it is the best night for kaley as well....of she said yes!"
As for the previous snapshot Cook is referencing, the newly engaged lovebirds were at Target when he jokingly asked Kaley to marry him with a plastic diamond. "You say these things".
"Yes! I say yes!"
Speaking previously, Kaley said: "I feel very, very lucky that I found someone like him". You always seem so happy when you're with Karl.
"Who knew my prior post was oracular", Cook captioned it. The actress told People magazine shortly after she began dating Cook following her divorce, "I don't know what the path is going to take, but I'm very happy right now". He also shared a photo of the stunning engagement ring that he chose for his soon-to-be wife.
She wrote alongside the video: "Still crying".
He popped the question on her 32nd birthday at their home in LA.
This will be the second marriage for Cuoco, who split from tennis player Ryan Sweeting in 2015, almost two years after their wedding. It's the best relationship she has been in.
