Kaley Cuoco is paying tribute to her infant daughter – with some bling!

The new mom, who welcomed her first child with boyfriend Tom Pelphrey, 40, in March, took to Instagram to share a picture of herself with her dog as she sported a gold and diamond nameplate necklace that spelled out daughter Matilda’s name.

The Big Bang Theory star captioned the post, “I better still be the favorite even with that new little human hanging around…” 

The 37-year-old announced the birth of her child on Instagram in April 2023 with the caption, “3-30-23 Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives! We are overjoyed and grateful for this little miracle. Thank you to the doctors, nurses, family, and friends who have helped us immensely over the last few days. We are blessed beyond belief. @tommypelphrey didn’t think I could fall even more in love with you, but I did.”

The actress and the Ozark alum confirmed their relationship in May 2022. The couple had met through their shared management team.

She was previously married to professional tennis player Ryan Sweeting from 2013 to 2016 and to equestrian Karl Cook from 2018 to 2022. Cuoco does not have any children from past marriages or relationships.
