Baby girl Pelphrey coming 2023 beyond blessed and over the moon… I (heart emoji) you @tommypelphrey!!!" Kaley Cuoco captioned their photo while Tom Pelphrey is holding a piece of cake with pink frosting.

Cuoco, 36 and Pelphrey, 40 shared happily on their Instagram stories and posts that they are expecting and waiting for their baby.

"And then it was even MORE BETTER. Love you more than ever @kaleycuoco," Pelphrey wrote on his Instagram post.

In one slide, Cuoco shows her already noticeable bump as she introduces "the bub to the horses," adding a sticker that reads "brb off to cry."

She also uploaded baby onesie outfits and a heartwarming shot of her holding her pregnancy test revealing the positive result while the couple looked lovingly at one another.

Another snap features the actress standing in front of a mirror showing her new body shape in a white tank top. She also included a photo of her and the actor as the soon-to-be dad stands behind her holding her waist.

The actress was previously married to Karl Cook from 2018 to 2022. Before that, she was married to Ryan Sweeting from 2013 to 2016.

After her second divorce, Cuoco said that she does not want to get married again.

In an interview with Extra at the premiere of her new movie Meet Cute, she said that she and Pelphrey met and had a "love at first sight" moment at the premiere of Ozark in April.

Cuoco told USA today, "'We have the same manager (Andrea Pett-Joseph), and we were set up by (her), which is so Hollywood."

"She's like, "Oh my God, I think you guys are perfect for each other,"' she recalled.

The couple confirmed their relationship in May and made their first public appearance as couple at The Flight Attendant executive producer Greg Berlanti's Hollywood Walk of Fame dedication ceremony.

The couple then made their red carpet debut at the 2022 Emmy Awards where both were nominees.

Cuoco was nominated for Outstanding Lead Actress in a Comedy Series for the second year in a row for her acclaimed HBO Max dark comedy thriller The Flight Attendant. She plays Cassie, an alcoholic flight attendant who has risky trysts with her passengers.

Pelphrey, meanwhile, was also a nominee for Outstanding Guest Actor in a Drama Series for Ozark.

"You see your life going one way, and then it's the direct opposite way," Cuoco said in an exclusive interview with Cosmopolitan on April 2016.

"I'm waking up going, 'Oh my God, my life just flipped upside down,'" she continued.
