The 36-year-old actor and filmmaker reposted the image, saying he is "Making room for new and beautiful things to come in 2018!"

The news makes Ferrera the newest (and the last) member of the "Sisterhood of the Traveling Pants" to become a mother. Alexis Bledel and Amber Tamblyn have one child each, while Blake Lively shares two kids with husband Ryan Reynolds.

It was definitely an incredible end to 2017, considering Ferrera ended 2016 with a Dec. 31 FaceTime chat with her "Sisterhood" BFFs, which she later described to James Corden at his "Late Late Show" as the girls' subtle way of making her jealous.

The 33-year-old "Ugly Betty" star first met Williams when she was cast for his student film while he was still at the University of Southern California.

After dating for several years, the couple got engaged in 2010. Talking to People shortly after their engagement, Ferrera shared what drew them together.

"We kind of connected from the get-go on that professional level and that was something that really drew us to each other, a shared passion for what we do and our work," she shared.

They were married a year later in 2011, in what sources said was an intimate ceremony among close family and friends.

Last summer, the couple took a vacation in Iceland to celebrate their 12^th year together. Ferrera boasted their romantic trip over at Instagram, with photos showing them obviously having a great time.
