Kaley Cuoco lovingly congratulates Tommy Pelfrey on his first Father's Day as a dad to baby Matilda.

Kaley Cuoco can't help but praise her little family.

On Father's Day Sunday, the flight attendant actress made sure to tell her partner Tommy Pelfrey how much she appreciates him and how much she loves raising their daughter Matilda together.

Cuoco posted a series of the most adorable photos of Pelfrey playing and cuddling with little Matilda, and ended her post with an equally lovely photo of her own father (Matilda's grandfather) having fun with his granddaughter.

"Happy (first) Father's Day to Tildy's favorite!" <3 you forever and appreciate all you do for our family! And to my dad ! The greatest pops and gramps on earth! Matilda is one lucky widdle chunk!"

Cuoco and Pelfrey welcomed Matilda in March 2023, less than a year after they first met in April 2022.

Since then, it has been nothing but bliss for the three of them.

Cuoco's "Flight Attendant" co-star Rosie Perez recently said, "She is so happy. Her love for her kids and her love for Tommy ...... Because I knew Tommy before I knew Kaylee. So it's been so wonderful."

Pelfrey also commented lovingly on what a wonderful mother Cuoco is.

"Oh, she's so cool. She's so good. It's like I love Kaylee a hundred times more. She's so funny and nurturing and easygoing and playful and loving ...... I mean, she's very affectionate. I mean, very affectionate.
