The Big Bang Theory's Kaley Cuoco said she would marry fiancé Ryan Sweeting anytime. And talk show host Ellen called her bluff when she appeared on yesterday's show - apparently, Kaley wasn't bluffing! Check out the impromptu ceremony below!

"I am very, very happy," Cuoco said of her engagement to tennis player Ryan Sweeting. "So happy. Life is so good right now. I cannot even tell you", adding that it was love at first sight for the happy couple.
