The Big Bang Theory's Kaley looked shocked in an emotional video posted by her now-fiancé Karl, as she burst into tears while showing off her new engagement ring.
"Honey? How do you feel honey? What's on your finger?" professional equestrian Karl asks Kaley as she covers her face with her hands, before showing her sparkling new ring to the camera.
"We're engaged" Kaley exclaims, as husband-to-be Karl interrupts to tell her she hasn't said 'yes' yet.
Just before his video post, the couple shared another photo of themselves out Christmas shopping where Karl appeared to be buying his girlfriend a joke engagement ring, however she appears to be unimpressed with his larking about.
"Who knew my prior post was oracular. 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.....of she said yes!!!!!" Karl captioned the engagement video on Instagram.
In the video Kaley can be seen wearing a black t-shirt and tracksuit pants, her hair in a messy high pony tail.
Romantic Karl, who has been dating the actress for two years, posted a photo of the stunning engagement ring he presented his bride-to-be, and thanked Nabis Diamonds for making it.
After she said yes, the happy couple shared a together, as Karl films the intimate moment Kaley tells him "I love you so much."
"In life, there is nothing like dancing right after getting engaged," he captioned the video of the couple sharing the obviously special moment, before continuing: "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 will be 31-year-old Kaley's second marriage. She was previously married to Ryan Sweeting, however the couple divorced after only 22 months.
The Big Bang Theory star wed the tennis ace on New Year's Eve in 2013, after a whirlwind romance, however speaking on U.S. breakfast show This Morning Kaley made it clear she has no regrets about tying the knot with Ryan.
"You know what, I'm not ashamed of anything that happened," she told the show's hosts. "I fall in love really hard, I do. I go deep. That person is it for me. And I love hard. And when it's over, it's over, and some people make mistakes."
She quickly corrected herself, adding, "(I) wouldn't call it a mistake; it just is what happened in my life, so I'm excited to see what the future holds. It happened and now I have to say I'm happier than I've ever been."
