 Prior to the big reveal, the actress documented her special evening with her now husband-to-be. Cook, 26, sent her flowers, set up a romantic candlelit dinner and gifted her with a one day trip to Disneyland. “I can’t even,” Cuoco captioned a pic of a piece of paper, which revealed their future traveling plans.

 Cook didn’t let a small sidestep ruin her big night, either. Before popping the question, he accidentally hit his head on a chandelier and began to bleed.

 Earlier in the day, Cook joked about getting Cuoco a fake ring during a trip to Target together. “On my loves birthday I got her everything she has always wanted….now judging by her face maybe not, it’s the thought that counts right,” he wrote. 
 
 Back in August, Cuoco gushed to Us Weekly that she hoped the relationship would go the distance. “I couldn’t be happier. I feel very, very lucky that I found someone like him,” she said at the time. 
 
 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 @normancook A post shared by Karl Cook (@mrtankcook) on Nov 30, 2017 at 11:07pm PST 
 
 As for why they are a good match? “Because I like to torture him and he doesn’t get mad at me. He just lets me do it! I’m just constantly trying to rib him. He’s got such a great sense of humor,” she added to Us. “I like it when I’m bugging him and then I finally get that laugh, which just kills me. He’s a real person and I think the big deal was knowing how much he loves dogs and horses — that’s always on my checklist. ‘Must love dogs’ is number one and he checked that off quite quickly and I fell very hard.”

 Cuoco and Cook have been dating since March 2016. They made they red carpet debut at the Longines Masters Los Angeles Gala in Long Beach, California, that September.

 Cook also shared a close-up shot of the gorgeous pear-shaped diamond ring he presented his bride-to-be after nearly two years of dating. 
 
 “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,” he said. 
 
 Just hours before sharing the proposal on social media, Cook teased Cuoco with a fake ring while shopping at Target. 
 
 “On my loves birthday I got her everything she has always wanted….now judging by her face maybe not, it’s the thought that counts right,” he shared. 
 
 Cook had his love in tears even before he gave her the real ring as he treated the Big Bang Theory star to a romantic candlelit dinner at their home. Cook prepared the meal himself and even made a menu as if they were at a restaurant. He made sure to serve all her favorite foods, including Moose Tracks ice cream. 
 
 Cuoco and Cook, who both love of horses, started dating in spring 2016 and made their first public appearance as a couple in September that same year. She split from husband Ryan Sweeting in the fall of 2015, filing for divorce after 21 months of marriage. (The proceedings were finalized in May 2016.) 
 
 Asked by PEOPLE in August, if marriage is in the cards again, Cuoco said that she’s “open to anything.” 
 
 “I don’t know what the path is going to take,” she said. “But I’m very happy right now.”
– Big Bang Theory star Kaley Cuoco is engaged, and she shared her own tearful reaction in this Instagram video. "We're engaged!" the 32-year-old says while fiance Karl Cook, 26, shoots the video. (He also has to remind her that she hasn't actually said "yes," and she happily complies through laughter and tears.) This is marriage No. 2 for Cuoco, who had previously been wed to Ryan Sweeting, notes US Weekly. She has been with Cook for about two years. One thing that brought them together: horses. Cuoco loves them, and Cook is a professional equestrian, notes People.
