Big Bang Theory's Kaley Cuoco flaunts tattoo in sexy bare-backed dress: 'My heart just exploded'

Kaley Cuoco has managed to spark a frenzy with a touching picture post, oozing sex appeal and melting hearts at the same time. Taking to Instagram, The Big Bang Theory star shared one of the most adorable moments with her pup Norman, and what followed next was a flurry of emotions from her fans.

Kneeling down to look at her pitbull in the eyes, Cuoco posed for a sweet black and white snap; with her adorable dog paying full attention to her. The actress even added a cheeky caption alongside the image.

"Trying to explain to #norman he will always be my prom king now and forever ♥ almost 9 years together!!!" the Penny actress wrote, sharing the post with her 3.5 million followers. While most people got all emotional seeing her bond with the pup, others couldn't help but notice the sultry side of the photo.

Baring her back for the camera, Cuoco offered a glimpse of the gigantic moth tattoo adorning her nape to the fans as she posed with her dress unzipped to the waist. The sitcom actress initially had her wedding date inked on her back, but after splitting from Ryan Sweeting, Cuoco covered it up with a dark moth design.

"Is that a Luna moth on your shoulders? It looks awesome! Would you post a colour pic please?" an excited fan commented, as someone else gasped, "My heart just exploded."

"Such a great shot of the two of you, Norman is such a lucky pupdog, God Bless You Miss Kaley!!!" a third fan added, echoing the feeling of many other users, who were touched by her latest upload.

"That's one handsome puppy and his momma has an ass kicking moth tat," shared one Instagram user.

Another added, "It looks like Norman is listening to you patiently so he can say he feels the exact same love for you #faithfullyfriends."

Cuoco, whose Instagram account is frequented by her furry pets, of late has been a glimpse into her romantic world with fiancé Karl Cook. The couple got engaged last month and like always, shared the milestone with their fans and followers on social media.

"Who knew my prior post was oracular. Well, after nearly two years, I finally got up the courage to ask her to marry me. This is the best night of my life and I think the video shows it is the best night for Kaley as well.....of [course], she said yes!!!!!" her boyfriend captioned the proposal video on Instagram.
