Kaley Cuoco Hot Girl of the Day. Mrs. Cuoco is one of the stars of the television show The Big Bang Theory. I've always been a big fan of the show and an even bigger fan of Kaley. She basically hangs out with a bunch of nerds on the show if you haven't seen it. Nothing like a down to earth chick that hangs out with geeks like myself. Haha, check out the hot pictures in the gallery below.
