Fans of Big Bang Theory star Kaley Cuoco are no stranger to her PDA-filled pictures with her boyfriend Karl Cook. But this time, surprisingly, it was her animal loving boyfriend, who was treating their fans to adorable glimpses of their day to day life – namely Cuoco sleeping her way through an episode of Game of Thrones.

Taking to Instagram, 26-year-old Cook posted an adorable photo of the Penny actress, showing her curled up with their furry friends on an extremely comfortable-looking couch.

And in the description, the ever-loving boyfriend couldn't help but gush about the actress and their regular couple activities.

He wrote, "It's so great watching game of thrones with my love @normancook, there is such a great repartee that builds on the ebbs and flows of this epic show," alongside the sweet snoozing photo of Cuoco.

Indeed the image sweetly captured Cuoco in a private moment with her pooches by her side, and just like her boyfriend, even the star's social media followers seemed to be in awe of the photo.

One fan exclaimed, "Ahhh the epic g.o.t girlfriend struggle. It's real," referring to Cuoco dozing off midway. Another fan gushed, "I love this picture. It's so sweet."

"Three snuggle bugs," someone else wrote talking about the cute trio huddled-up together on the couch, as a second user added, "That honestly looks so comfortable that you cannot blame someone for falling asleep."

Now, loyalists would know that this is not the first time that Cuoco's boyfriend has poked some harmless fun by sharing one of her candid snaps on the picture-sharing site. Considering that the actress had replied to one of his last such post with "I hate you", one fan jokingly said, "If I were kaley, i would kill you!"

Cuoco and Cook frequently share their romantic moments with their fans and most recently it was a dreamy picture under a sky with two rainbows that had melted hearts on Instagram.

"Love struck and weak in the knees," the TV actress captioned the mesmerising snap.
