Kaley Cuoco gives birth and welcomes her first baby with Tom Pelphrey

He proved he was up to the task of partner and dad with several sweet gestures towards Kaley during her pregnancy. In December, he gave Kaley a note written in Sharpie blue on the back of an envelope that read, “Hey baby, me and King are sleeping upstairs. Love you!”

Kaley explained that the Monk the actor helped her get some much-needed rest when one of their dogs was sick. “Best baby daddy ever,” the Big Bang Theory alum wrote on her Instagram Stories on Dec. 14. “When our little KING is sick and coughing then @tompelphrey takes him to sleep with him so I can sleep.”

Tom also made Kaley’s recent 37th birthday one to remember. He shared a photo gallery on Instagram in November and captioned it, “Happy birthday to my favorite person in the world. Love you!”

Kaley shared a bit more of her special day posting with Tom, writing, “This birthday week has been so special…So many friends and family to thank and acknowledge the outpouring of texts, posts, of prezzies and generally making me feel incredibly loved. You know who you are and to my lifelong buddy @tommypelphrey for being a true partner. I feel super blessed and unworthy at times. My heart is full.”
