Uzo Aduba is celebrating joining the motherhood club.

"I'm a Mommy you guys," Aduba wrote in the caption of an Instagram post Thursday as she introduced the world to Adaiba Lee Nonyem.

The "Orange is the New Black" actor, 42, included two photos of herself in a hospital bed with her newborn.

"My daughter. I've never been in love so quickly, so deeply in my entire life. I really don’t know what to say, guys. My heart is full," Aduba wrote. "Thank you, God. I have joy like a fountain. I have witnessed a miraculous thing, and I feel blessed to know you are ours. We love you so much, Adaiba Lee Nonyem."

The first-time mom, who is married to filmmaker Robert Sweeting, said the name they chose means she is "daughter of the people, treasurer of the mother’s names who came before you."

Friends from Jessica Chastain to Naomi Campbell, Gigi Hadid, Gabrielle Union, Dakota Fanning, Iman, Lena Waithe, America Ferrera and Niecy Nash congratulated Aduba on the addition to the family.

"You are so beautiful and deserve every moment of all the fountains of all the joy! Congrats!" Chelsea Handler commented.

"Congratulations," Octavia Spencer wrote. "You're glowing."

Aduba debuted her baby bump at the Tony Awards in June and announced her pregnancy that same day.

"I know as the three of us continue to grow, our only, ONLY goal will be to love you, little one," she wrote in the caption of her June 11 Instagram post. "My goodness. Look what God has done."
