The size of the ring.

Actress Kaley Cuoco has announced that she is engaged to boyfriend Karl Cook. She has been dating Karl, who is a professional equestrian, for two years. He popped the question on her 32nd birthday at their home in LA. He managed to capture her reaction and she posted it to Instagram while announcing the news. She said, "Still crying, every part of this night has been perfection just like you @mrtankcook I love you forever!" The poor girl can barely talk she is crying so much.

Still crying ? every part of this night has been perfection just like you @mrtankcook I love you forever!

He followed up with a sweet video of them hugging, saying, "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"

And just take a look at the ring he got made for her. It's a rock.
