Kaley Cuoco is starting the new year with love!

The Big Bang Theory star took to Instagram on Monday to share a sweet New Year's message to her fiance, Karl Cook, thanking him for ending the year with "perfection." Cook proposed to Cuoco on her 32nd birthday on Nov. 30 after a year and a half of dating. 

"Here’s to you , love. You made 2017 end with perfection ?can’t wait to ? the Cook for all the years to come... #kcsquared @mrtankcook," Cuoco captioned a shot of herself lovingly looking at her beau, who is staring into the camera. 

Cook, meanwhile, celebrated the New Year with a silly pic of his fiancee, who seemingly just couldn't stay up for 2018. 

"I like starting the year off with a good chuckle. Here's @normancook really trying to stay up to the new year," he wrote. "It was only 9:30, good effort. I love you so much honey." 

Cuoco and Cook recently opened up about their romance to Sidelines, revealing that they are "each other's true half." 

"We met at Thermal in 2016 and the day we met I actually ended up asking her out to dinner. We went to dinner that night and we’ve been together ever since,” Cook revealed. “We met each other because of horses. Horses are a big part of our lives individually and together it’s amplified because it’s something we share and we can do it together.”
