Kaley Cuoco has once again poured out her love for boyfriend Karl Cook on Instagram. The actress posted another picture of her with Cook recently. It seems that the Cuoco can’t stop gushing about boyfriend Cook. She is apparently happier than ever in her new relationship.

She wrote a beautiful caption along with the picture. “When you realize your cheeks haven't stopped hurting #thisguy thank you @claudcraig for capturing a little bit of magic.” Cuoco quite often posts pictures with Cook, declaring her love for him. Karl Cook, 25, is the son of Intuit software co-founder and billionaire businessman Scott Cook.

Last month a source had told E Online that Kaley Cuoco is “super smitten” by her boyfriend and is “head over heels” in love with him. The couple is often spotted together. Cook accompanied his ladylove to the Golden Globe Awards as well. They were also together at the Golden Globes afterparty.

Cuoco and Cook seem to be inseparable. They have been travelling together a lot in the recent past. Last month, they were spotted taking a romantic stroll on the streets of Beverly Hills. The couple walked hand-in-hand while shopping there. On Nov. 30, Cuoco celebrated her 31st birthday with Cook in California.

Kaley Cuoco and Karl Cook look happier than ever together. The actress had announced about her relationship in September 2016. They reportedly started dating in March last year. “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,” Cuoco had told “The Talk” show host Sharon Osbourne in September. “He's an amazing rider, amazing equestrian, and a great human. We shared a passion for horses and dogs. It's been lovely.”
