He then shared a photo of her ring and man, that's one spectacular diamond!
The star of "The Big Bang Theory" exclaimed "We're engaged!" after boyfriend Karl Cookproposed to her in a video he posted Thursday ― Cuoco's 32nd birthday. How do you feel, honey?
"What's on your finger, honey?" he asks. He posted a video of a very emotional Cuoco - who finally stopped crying long enough to say "yes" - following the proposal.
The 26-year-old Cook said in the caption of the video that the engagement comes after almost two years of dating.
"I've had that handle since I started Instagram - way before I met Karl - but when I met him, he thought it was really weird and I said, 'I had that way before I met you, mister.' But it is a coincidence", she said, laughing.
"In life, there is nothing like dancing right after getting engaged", he said. She has been dating Karl, who is a professional equestrian, for two years. "I think that that's what makes us so strong and really happy". Thank you @nadis_diamonds for making the greatest ring I could hope for.
He also shared a sweet video of the couple dancing after she said yes. Kaley had gotten engaged to Ryan after just three months of dating, and they were married for 21 months before separating.
They held their wedding on New Year's Eve 2013, and in September of 2015 they publicly revealed that they were splitting up.
This will be the second marriage for Cuoco, who split from tennis player Ryan Sweeting in 2015, almost two years after their wedding.
When the divorce was finalized last May, Kaley got to keep all of her money from The Big Bang Theory thanks to the prenuptial agreement, according to TMZ.
