Kaley Cuoco has given birth to her first child with boyfriend Tom Pelphrey. “Introducing, Matilda Carmine Richie Pelphrey, the new light of our lives!” the “Meet Cute” star wrote alongside a slideshow of photos of her newborn daughter on Instagram Saturday. “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 💗.”

The first-time mom concluded with a message to her boyfriend, saying, “@tommypelphrey didn’t think I could fall even more in love with you, but I did.” Cuoco also shared in the post that Matilda was born on Thursday.

The actress, 37, first surprised her Instagram followers with a pregnancy announcement in October. “💕Baby girl Pelphrey coming 2023💕,” the then-expectant star captioned a slideshow at the time. “beyond blessed and over the moon,” she continued. “I 💓you @tommypelphrey !!!”

In a post of his own, the 40-year-old “Ozark” alum gushed, “And then it was even MORE BETTER. 🎀🎀🎀. Love you more than ever @kaleycuoco ♥️🙏♥️.” The reveal came five months after the couple made their relationship Instagram official. Cuoco, who was previously married to Ryan Sweeting and Karl Cook, called her bond with Pelphrey “love at first sight.”

The “Flight Attendant” star explained to “Extra” in October that she and the actor met because they have “the same management team.” She added, “My manager actually took me as her guest to the ‘Ozark’ premiere, and I met him there. It was like the angels started singing. I was like, ‘Hallelujah.’ It was very magical. … It was perfect.”

Cuoco and the “Outer Range” star met after she underwent “a lot of therapy and self-reflection.” After announcing their expanding family, the duo continued to document the Golden Globe nominee’s pregnancy progress — including her “horribly sick” first trimester. “We’re so excited,” Pelphrey told “Extra” in an October interview. “It’s the most incredible thing.”

The former soap star concluded by calling himself “very blessed, very fortunate [and] very lucky.”
