Kaley Cuoco has revealed she's pregnant with her first child.

The Big Bang Theory actor made the big announcement by posting a series of photos on social media.

She and her partner, Tom Pelphrey, were beaming from ear to ear in the snaps showing their pregnancy journey.

The images included the couple with their pregnancy test, along with what looked like a gender reveal cake.

The cake indicated they were expecting a girl.

Kaley wrote: "Baby girl Pelphrey coming 2023...beyond blessed and over the moon."

People were quick to shower the couple with praise and congratulatory messages.

One fan wrote: "CONGRATS! Incredibly happy for you! Woo hoo!!!!"

Another said: Congratulations!!! Blessings all the way!!!"

A third added: "Ahh congratulations beauty! This love baby will be soooo blessed to have you as a mom! You’re going to be amazing."

Kaley and Tom have been dating for five months and they met at a premiere event for the hit Netflix show Ozark.

She explained to USA Today how they ended up getting together.

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

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

Cuoco added: "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. 

"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."
