America Ferrera, known for her roles in television shows and films like Ugly Betty and Sisterhood of the Travelling Pants, took fans by surprise last New Year's Eve.
The actress and her husband, Ryan Piers Williams, revealed they had their first child on the way in an adorable Instagram post.
She posted a photo in which she's posing alongside her husband wearing goofy "2018" glasses and holding up a onesie.
"We're welcoming one more face to kiss in 2018!" read the caption.
Ferrera and Williams first met when Williams cast the Emmy-winning actress in his student film at the University of Southern California.
They dated for a few years before getting engaged in 2010.
"We kind of connected from the get-go on that professional level and that was something that really drew us to each other," Ferrera told People. She added that they have "a shared passion for what we do and our work."
The Emmy-winner and Williams finally tied the knot in 2011 in "an intimate setting amongst close friends and family."
Her former co-stars, Blake Lively, Alexis Bledel, Amber Tamblyn and Vanessa Williams, all showed up for their big day.
A few years later, Ferrera and some of her Ugly Betty co-stars reunited for another special occasion: her baby shower at Beauty & Essex Los Angeles.
"No poopie diaper games here. Just dancing, drinking (water for me ðŸ¤—), and some of the people we love to celebrate the little human we can't wait to meet," Ferrera wrote in the caption of photos from the party on Instagram.
The celebration continued the following month, but this time with was with her Sisterhood of the Travelling Pants co-stars. They also had some important childbirth and motherhood advice with the mom-to-be.
"They all were like, "˜get the drugs,' " Ferrera, 33, told People. "So we'll see if I do. But I think it's a very sound piece of advice."
Lively, Bledel, and Tamblyn have all been moms for a while now, and now Ferrera has joined the club.
Nearly seven years after saying "I do," Ferrera and Williams once again took to Instagram to announce that they have welcomed their first child.
"When 2 becomes 3 ... Welcome Sebastian Piers Williams "“ aka Baz! Mom, Dad and Baby are happy, healthy and totally in love!" Ferrera captioned a sweet photo of her newborn son's toes.
Ferrera's A-list followers were quick to comment and congratulate her and Williams on their new arrival.
"He is the most divine thing I've ever held in my arms. I love you," wrote Tamblyn.
"Welcome to the world little one!! Congrats America & Ryan," commented Reese Witherspoon.
Ferrera is just the lastest celebrity to welcome a baby in the last few weeks.

Jordin Sparks and Dana Isaiah
Six months after announcing their secret marriage, American Idol winner Jordin Sparks and her husband became first-time parents to a son named Dana Isaiah Jr., also known as DJ.
There were a few complications during his birth, after the umbilical cord got wrapped around his neck, but the midwife quickly came to the rescue.
"It was just this incredibly miraculous, beautiful moment that I don't know could ever be duplicated," said Sparks, who attended the premiere of her movie just three days after giving birth. "You see in movies how emotional people get, but until you are actually sitting there ... it's beyond anything I've ever felt in my life."
Kristen Dunst and Jesse Plemmons
The actor couple is notoriously private, so they have kept all details of their newborn baby under wraps.
Dunst showed off her baby bump when she appeared in Rodarte's 2018 Lookbook earlier in the year, but she hasn't commented on her journey into motherhood.
However sources close to the couple have confirmed that they welcomed "a healthy baby boy" over the weekend of May 12.
"Everybody is doing great," added the source.
Congratulations to Fererra, Williams, and all the couples who welcomed babies this month!
