The Big Bang Theory star has said yes to her professional equestrian rider boyfriend Karl Cook, after he popped the question following nearly two years of dating.
Karl revealed the happy news with an emotional post to show the actresses reaction.
The video clip shows a stunned and overwhelmed Kaley crying whilst cradling her head in her hands.
“Well after 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,’ he captioned the post.
Karl can be heard asking: “What’s on your finger, honey?”
“We’re engaged,” Kaley replies.
But then Cook reminds her: “You still haven’t said yes yet.”
The equestrian then posted a video of the pair dancing, writing, ‘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.’
The sports star also posted a pic of Kaley’s stunning engagement ring, saying: I am so so so happy. Thank you @nadis_diamonds for making the greatest ring I could hope for. Absolutely brilliant. Thank you thank you.
Kaley also shared the emotional video.
‘Still crying. Every part of this night has been perfection just like you @mrtankcook I love you forever!’
This is Kaley’s third engagement. In 2011, she became engaged to Josh Resnik, but they broke it off just months later.
Then, in September 2013, tennis player Ryan Sweeting popped the question, with the couple marrying just four months later on New Year’s Eve.
However, two years later, they decided to split, with their divorce being finalised in May 2016.
Kaley began dating Karl in late 2015 just months after splitting from Ryan.
