Cuoco has also opened up about how her pregnancy has had its ups and downs, revealing on her Instagram Story that she experienced morning sickness in a photo with stunt double Monette Moio.

"Hey @monettemoio remember that time we shot an action film while I was pregnant and horribly sick and you had to take care of me and be me and do all the things as non pregnant me?!," the actress wrote.

In another photo shared Tuesday, Cuoco relaxed on a bed slightly curled up with her eyes closed which she shared alongside a sticker of the nauseous emoji. Addressing the morning sickness again, she wrote, "This was every day between setups lol."

Cuoco previously spoke in an interview with USA Today about how she and Pelphrey were introduced to each other for the first time — an interaction she deemed, "love at first sight."

"We have the same manager [Andrea Pett-Joseph], and we were set up by [her], which is so Hollywood," Cuoco told the outlet. "She's like, 'Oh my God, I think you guys are perfect for each other.'"

The two met at the Ozark premiere in April and sparks flew instantly.

"I heard his voice, and I turned around, and it was like my life was over, or just starting. It hit me. It was love at first sight," she recalled. "We were immediately connected. I do feel like I've known him my whole life, but I wasn't ready for him."

"We're ready to build a life together," she added.
