The 27-year-old actress told People magazine that she's so madly in love she would marry fiancé Ryan Sweeting tomorrow if she could.
Kaley and tennis pro Ryan hit the headlines in September when they confirmed their engagement after only three months of dating, but Kaley later said it had been love at first sight and she knew he was 'The One'.
She told People the pair are aiming for a wedding in early 2014, adding: "I want to marry him tomorrow so I want to go as fast as possible."
Kaley, who plays waitress Penny in Big Bang, told ET Online last month that she understands why eyebrows were raised after their quick courtship but she knows it's right.
"From day one I just knew immediately and it's been magic. We have all the same family friends," she explained. "We grew up with the same people, we just never met. So I kind of feel that I've known him my whole life. I know that it seems a little crazy on paper, but it's what works for us."
Kaley has revealed that she had no idea Ryan was planning to pop the question as he actually picked a fight with her before presenting the ring.
But while Kaley is basking in a newly-engaged, nearly newly-wed glow, there was disappointment for the Cuoco family this week when her sister Brianna was knocked out of The Voice US by team coach Blake Shelton.
Kaley tweeted afterwards: "Bad move @blakeshelton !!!! #TheVoice nonononono @bricuoco killed it and couldn't have looked any hotter. #futurestar #movinonup."
