The Big Bang Theory actress Kaley Cuoco has welcomed a baby girl with her fiance US actor Tommy Pelphrey.

The 40-year-old, best known for starring as Penny in the smash hit CBS sitcom, and the 44-year-old Ozark actor welcomed their second child, Philomena Carmine Bobby Pelphrey, on October 12.

The pair had their first child, Matilda, in March 2023.

In a heartfelt post on Instagram, Cuoco said their family was now “officially complete” and shared a string of photographs of their newborn.

She said: “There are no words to describe this feeling once again. What a blessing.

“We are so grateful for the crazy wild up and down journey that brought us to our little Philo!

“Family officially complete. Time to bring Matilda’s baby home!

“Tommy Pelphrey life exploded the minute we met, and the gifts keep coming. I love you forever, girl daddy!”

She also posted an Instagram story of her daughter Matilda with the caption: “Someone waiting at home for us!”

Twilight actor Taylor Lautner was among the celebrity friends who congratulated the couple in the comment section. It comes just weeks after he welcomed his first child.

Cuoco revealed in June that the couple were expecting their second child and shared a carousel of photographs, including the couple and their daughter with a gender reveal cake, showing pink sponge inside.

Prior to starring in The Big Bang Theory, which ran from 2007 to 2019, Cuoco appeared as Bridget Hennessy in the sitcom 8 Simple Rules.
