It looks like things are heating up between Kaley Cuoco and Karl Cook!
The Big Bang Theory actress is "in love, head over heels" with her boyfriend, a fellow equestrian, a source told E! News exclusively.
"They seem to be in a good spot right now. She is always traveling with him. It's not as much her schedule but more so his. She never knows when she's going to be in town because she goes whenever and wherever he goes," the source said, adding, "She is super smitten."
