Kaley Cuoco, Tom Pelphrey expecting first child together: See their pregnancy announcement

Kaley Cuoco is getting ready to become a mom.

The "Flight Attendant" and "Big Bang Theory" star, 36, announced on Instagram Tuesday that she is expecting her first child, a daughter, with fellow actor Tom Pelphrey, 40.

"Baby girl Pelphrey coming 2023," Cuoco wrote. "beyond blessed and over the moon… I (love) you @tommypelphrey !!!"

Along with the caption, Cuoco shared a series of photos of her and the "Ozark" actor with a cake with pink frosting on the inside.

In another photo, Pelphrey holds up a baby onesie bearing the words "love my daddy," and, in another, Cuoco smiles with him while holding up several pregnancy tests.

Cuoco opened up about her relationship with Pelphrey to USA TODAY in May.

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

Cuoco added she met Pelphrey at a Netflix "Ozark" premiere in April.

"I was standing with Andrea and Tom walked in, and I heard his voice, and I turned around, and it was like my life was over, or just starting," she said. "It hit me. It was love at first sight. 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."

Cuoco was married to equestrian Karl Cook from 2018 to 2021 and tennis player Ryan Sweeting from 2013 to 2016.

"I will never get married again. I would love to have a long-lasting relationship or a partnership. But I will never get married again. Absolutely not. You can literally put that on the cover," she bluntly told Glamour in April. "But I believe in love because I’ve had incredible relationships."

Cuoco added, "I do believe there is someone out there. I love love. I’m not someone that wants to be by myself. I just need to figure out my priorities a little bit and make sure now I know that I need to water that relationship."
