'Ugly Betty' actress America Ferrera is now a mother.

The Golden Globe-winning actress gave birth to her first child on Tuesday, she confirmed on social media with a sweet picture of her baby's little foot. She went on to reveal her son's name as well as his nickname. 

"When 2 become 3...," the star captioned. "Welcome Sebastian Piers Williams - aka Baz!"

"Mom, Dad, and Baby are happy, healthy and totally in love!" she added on the Instagram post. 

The Sisterhood of Travelling Pants star tied the knot with actor Ryan Piers Williams in 2011 and in this year's New Year, they revealed that their little one was on the way. 

While donning colorful 2018 glasses, the actress and her husband posted a snap on her Instagram with the caption, "We're welcoming one more face to kiss in 2018! Wishing you #MásBesos in the New Year! #babybesos #HappyNewYear."

America is the last member of the Sisterhood to become a mama, and immediately after announcing her pregnancy, she celebrated with her co-stars Tibby, Lena, and Bridget. The then-pregnant actress was joined by Amber Tamblyn, Alexis Bledel, and Blake Lively for another lovely Insta post. "Starting the New Year off with blessings from my Sisterhood. We've got work to do for the next generation. Let's get to it," the soon-to-be mom captioned the photo.

Then she recently celebrated her impending addition with a baby shower, attended by her former castmates from "Ugly Betty."

Their little one arrived just a few weeks ahead of his famous mom and dad's wedding anniversary on June 27.
