Cuoco posted a photo collage consisting of her photos with her friend Jamie Greenberg and her son Simon. Cuoco can be seen lovingly cuddling and kissing the baby. The caption of the photos read: "Nothing like starting the day with my Bff @jamiemakeupgreenberg and baby Simon! #mylittlebuddy #iaskedjamieificouldkeephim #shesaidno."

Noticing the hashtag, Enstarz noted that even though there is no formal announcement of Cuoco's plans of becoming a mother, she might be hinting that she could try to have a baby with Sweeting sometime soon.

Cuoco and Sweeting reportedly began dating in August 2013, when they were spotted together around Sherman Oaks in California. Thereafter, they were seen together on several occasions, including 2013 Emmy Awards red carpet.

In September 2013, the couple was said to be engaged. On Dec. 31, 2013, Cuoco and Sweeting walked down the aisle in much-talked about wedding ceremony and the couple now sports a tattoo representing their wedding date.

As for kids, a long time ago, Cuoco said that she is ready to have babies. Speaking to TV show host Ellen DeGeneres, Cuoco said, "We want to have kids, we can't wait."

Chatting with People in January, Cuoco reiterated her desire to have babies. She said that not only she loves children, but Sweeting does too and she is eager to start the "next part" of her life.

"You never know. I'm always coming up with surprises! Probably not tomorrow, but sooner than later," Cuoco said.
