Kaley Cuoco, 40, celebrated a friend's wedding over the weekend, offering a glimpse of her baby bump alongside fiancé Tom Pelphrey. The actress, who announced her second pregnancy in June, shared photos from the event via Instagram Stories on Sunday.

Cuoco, dressed in a pink empire-waist gown, was accompanied by Pelphrey, 43, and a group of friends. The evening included dancing and singing along to Marvin Gaye's "Ain’t No Mountain High Enough." Cuoco humorously captioned one post, "Zero fun was had," and another, "A time was had…didn’t go into labor, thank God."

Earlier this summer, Cuoco announced her second pregnancy with a family portrait that included Pelphrey and their three-year-old daughter, Matilda. The announcement featured a gender reveal cake, confirming that Matilda would soon have a baby sister.

In her Instagram caption, Cuoco expressed gratitude for the moment, writing, "Completing our little family, what a dream come true! This second time around journey has been a little windier in many ways, but wow we are so grateful for this moment!! Little sissy on the way!!! @tommypelphrey girl dad for life and yes, the last pic is our dainty princess giving us the middle finger!"

Cuoco and Pelphrey have been in a relationship for four years, meeting in April 2022. Pelphrey proposed to Cuoco, and they announced their engagement in August 2024.

Last November, Cuoco spoke with E! News about parenthood, addressing mom-shaming critics. She emphasized that "Every mom I can guarantee is doing the best they can," adding, "It's just this business, it's this life. It is what it is. But yeah, we got to stop at the shaming."

She also noted that her daughter Matilda, born in early 2023, is a happy child with abundant love, and that parenting approaches can vary. "I just feel like every kid is so different. What's good for your kid might not be good for mine," she stated.
