Naturally, the photo started off some comments from fans who were wondering if she was beginning to practice for her own day as a mom, whenever it would potentially come.

"hahahaha how else is she going to learn?" one fan commented.

While Cuoco isn't pregnant, she has broached the subject of babies with her husband of just under a year several times, with her most recently addressing talk about her possibly planning for a baby in September, where she said she needed to practice not losing her dog before she could be counted on to care for a child.

"We [want to have kids', we can't wait" she told Ellen DeGeneres. "We actually just rescused another dog, everyone that loves me knows I'm a big dog lover so I just got a really small one, a little rescue, her name's Ruby. And we do want to have kids, but I'm a little...I've lost this dog in the backyard so many times that I feel like I have to practice not losing her, so I don't actually lose my child."

"That's what I'm basing it on, because she's pretty white and noticeable, so I keep thinking if I can't find her..." she added.
