“Big Bang Theory” Season 10 star Kaley Cuoco and her boyfriend Karl Cook may have been dating for over a year now, but the couple is still in their honeymoon phase.

On Tuesday, Feb. 21, Cuoco took to Instagram to give her 3.2 million followers an update on her love life. She posted a new photo with Cook, in which the two of them rock matching round sunglasses. Both the actress and her equestrian beau kept it simple and casual, with Cuoco sporting a black tee and Cook a white one. In the caption, Cuoco seemed to imply that she hasn’t been able to spend a lot of time with her boyfriend lately when she wrote, “Missing my blonde buddy love.”

Cuoco’s followers gushed over the actress’ look and her sweet boyfriend in the comments. “So cute together,” wrote one fan. “You two compliment each other and I am so happy he makes you smile and laugh.” Another follower took notice of Cuoco’s flowing blond tresses, commenting, “Your hair is killer!!!”

This new photo comes after Cuoco shared a sweet snapshot of her and Cook at a furniture store last week. In the pic, Cook drops a loving kiss on Cuoco’s hair as the latter takes a mirror photo of them. The actress revealed in the caption that it was their first time shopping for furniture together.

Aside from showing off her relationship with Cook, Cuoco also posted a promo for a cause she supports. The actress shared a photo of herself wearing a black and white shirt with the words: “Speak for those who have no voice.” In the caption, she told her followers that they can get her adorable shirt from teespring.com until March 6 if they would like to support “ending puppy mills.” According to the actress, all the profit from the shirt sales will go to the production of a documentary titled “A Voice for Lil Olive,” which stars Cuoco and Lil Olive, whom she describes as “the most adorable little mill survivor.”

Cuoco also encouraged her followers to adopt dogs instead of buying them at pet stores. For those who would like to support the cause, she suggested visiting the website avoiceforlilolive.com to learn more about it and to follow the documentary’s official Instagram account.
