Kaley Cuoco can't stop gushing about boyfriend Karl Cook

Kaley Cuoco has no reservations when it comes to expressing her loving feelings for Karl Cook.

The 30-year-old was caught kissing her 25-year-old beau all over again but this time while riding horses, declaring on Instagram:

"Finding someone to share your truest passions with changes everything."

Other photos posted on social media are selfies of the duo in which Cuoco appears amazingly love struck and excited that Cook is by her side.

She told People why she’s gushing with public displays of affection.

"I think meeting people that are involved [in the same things as you] – I think that the horse connection is special,” she said.

A professional equestrian, Cook is also the son of billionaire businessman and Intuit co-founder Scott Cook.

In one particularly telling Instagram post, the "Big Bang Theory" star wrote, “That’s what happy looks like” while nuzzling with her nose the cheek of a beaming Cook.

In a second, more recent photo on Cuoco's Instagram account, Cook appears to be snarling even though his lady love is lovingly nuzzling his face. The caption says it all: "partners in crime."

After finalizing a messy divorce in May from her tennis player ex Ryan Sweeting, Cuoco has wasted no time in moving on.
