Wedding bells are ringing for "The Big Bang Theory" star Kaley Cuoco after being engaged to her longtime boyfriend and professional equestrian Karl Cook. The television star broke down moments after Cook proposed, and every second of it had been captured.

Cook posted a video of a teary Cuoco on Instagram after saying yes to his proposal. Cook 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... if she said yes!!!" And she did say yes.

Cook then followed the proposal video with another video of him and her wife-to-be dancing to the tune of Ed Sheeran's "Perfect." Cook captioned the video with "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."

The newly engaged couple were recently spotted having a nice time in Los Angeles, and Cuoco is all smiles.

Other television stars congratulated the couple on their engagement including Cuoco's fellow "The Big Bang Theory" star Kevin Sussman and "Scorpion" leading actress Katharine McPhee.

There are still no further updates if the two have already set a date for their wedding or not. Cuoco will surely have her hands full with "The Big Bang Theory" being renewed until season 12.

Cuoco is not the only "The Big Bang Theory" star celebrating about something new. The show's very own Bernadette, Melissa Rauch, recently welcomed her first child with husband Winston Rauch. The announcement was made through an Instagram post with the phrase, "It's a girl." Rauch captioned the photo with, "I am beyond over the moon to share that our beautiful baby girl, Sadie Rauch, has arrived and our hearts are bursting at the seams with love for her."

In the series, Bernadette is about to give birth to her second child with his one and only Howard Wolowitz (Simon Helberg).
