New mom Kaley Cuoco is celebrating her baby girl with some special bling.

The “Big Bang Theory” alum, who welcomed her first child with boyfriend Tom Pelphrey in March, shared a sweet Instagram photo Monday wearing a delicate nameplate necklace that spelled out daughter Matilda’s name in gold and diamonds.

Cuoco, 37, layered the piece with a colorful beaded floral necklace and captioned the snap from her dog Dumpy’s perspective: “I better still be the favorite even with that new little human hangin around…”

Cuoco also shared Instagram Story pictures cuddled up with little Matilda, as well as one showing off the infant’s teeny pink-and-white Nike sneakers ($45).

Cuoco’s far from the only celebrity mom honoring her offspring with jewelry; Kim and Khloé Kardashian, Kate Middleton, Blake Lively and Kylie Jenner are among the other famous mothers who’ve worn pieces adorned with their little ones’ names or initials.

The “Meet Cute” star introduced her daughter to her 7.8 million Instagram followers on April 1 with an emotional post after giving birth on March 30. 

“Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives!” Cuoco wrote. “We are overjoyed and grateful for this little miracle.”

Cuoco tagged partner Tom in the pic, writing that she “didn’t think I could fall even more in love with you , but I did.”

Cuoco and the “Ozark” alum, 40, confirmed their relationship in May 2022. 

The “Flight Attendant” actress was previously married to Ryan Sweeting and tennis player Karl Cook. 

She described meeting Pelphrey as “love at first sight.”
