Pelphrey celebrated the news with a post of his own, writing, "And then it was even MORE BETTER. Love you more than ever."

Cuoco was previously married to former professional tennis player Ryan Sweeting from 2013 to 2016. She wed equestrian Karl Cook in 2018, but the two split in September 2021 and finalized their divorce in June.

In a February interview with Entertainment Tonight, the actress admitted she was leaving most of the baby prep to Pelphrey.

"I have no plan, and I've read zero books. So, that's the type of mom I will be," Cuoco told the outlet.

"All the ways I'm not like a prepper. I'm just not that way. It's gonna be great, I trust the process. Tom has googled enough for the both of us. He could probably deliver this baby at this point.

"I'm just like, 'It's gonna be great,'" she added. "But that's how I’ve gone through life. I think nowadays we get so caught up, right? We didn't even have all this stuff at our fingertips, and now it's almost too much."

The California native added that she received valuable advice on parenting from a friend, who was also a new mother.

"My girlfriend I was on the phone with the other day 'cause I had a question about something, she has a newborn as well. I said, 'I don't know what I'm gonna do.' And she goes, 'Your baby's gonna tell you what to do.' And I love that," Cuoco said.

"I was like, I know I tell people what to do. If this child is anything like me, she's gonna be like, 'This is what I want,' and I just need to listen."

Cuoco told the outlet her mother was "thrilled" over her pregnancy and would be helping with her newborn.
