An E! Online report previously stated that Kaley is "super smitten" and has fallen "head over heels" in love with Cook. A source told the website, "They seem to be in a good spot right now. She is always travelling 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. She is super smitten."

Speaking about Cook, she told The Talk host Sharon Osbourne, "I am so happy... I can't stop smiling, life is so, so good. We met at a horse show, I finally found my horse guy. It was very meant to be."

"He's an amazing rider, amazing equestrian, and a great human. We shared a passion for horses and dogs ... It's been lovely," the actress continued.
