Talk about a big bang! Kaley Cuoco has a ring on her finger once again and she couldn’t be happier! Equestrian boyfriend Karl Cook proposed to the Big Bang Theory star on Nov. 30 (which is her freakin’ birthday, btw!) with the biggest ring we’ve ever seen, and her emotional reaction brought tears to our eyes! Watch the romantic proposal aftermath and see the stunning ring in the video below!

In the caption for the totally precious video, Karl wrote “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… she said yes!!!!!” With all those tears, we would say he’s probably right!

The same day, Karl teased his soon-to-be-fianceé by holding up an engagement ring Christmas ornament in Target while Kaley looks less-than-amused. “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???” We definitely hope they bought that ornament, though it’s just barely bigger than the huge sparkler he got for her finger. “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 gushed after the proposal. Aww!

We are so happy to see Kaley with someone who treats her like a total princess and makes her this happy, especially since she went through such a painful divorce from ex-husband Ryan Sweeting. Kaley got engaged to Ryan after dating for just three months, so we think it’s a good idea that Karl waited longer to make sure it was right. Congratulations, you guys!
