Lovebirds Kaley Cuoco and boyfriend Karl Cook are expanding their family! The Big Bang Theory actress took to Instagram earlier this week to announce that they have adopted an adorable dwarf mini-horse called Shmooshy.

In the image, Cuoco can be seen kissing her boyfriend as she poses with their new pet and their English bulldog. The caption reads, "The [horse] family expands welcome Shmooshy!!!!"

The adorable mini-horse even has her own Instagram account with almost 25,000 followers and 10 posts. The bio of the account reads, "I'm a rescued dwarf mini excited for a glam filled future".

In the account's first pic, Shmooshy poses with Cuoco as they both sport matching bun hairstyles.

The photo is captioned as, "Hi! my name is Shmooshy!

The adorable new pet has already returned with Cuoco to California, and she is already in love with the beach style. The Penny actor posted a picture of Shmooshy rolling around in the sand, and captioned it, "Blonde beach babe @lifewithshmooshy #bigbaycitymascot."

Karl Cook too joined in the fun and shared a glam photo of Shmooshy wearing a hat sideways. He captioned the image as, "When you are as cool as smooshy you can wear a big bay city hat tilted to the side. Smooshy now has her own insta @lifewithshmooshy everyone has to follow, she is the most precious ever."
