Katherine Schwarzenegger and Chris Pratt Welcome Baby No. 3

It's a...

Congratulations are in order for Katherine Schwarzenegger and Chris Pratt—the couple just welcomed their third child together and shared the news of their baby's birth via Instagram on November 11, revealing that Schwarzenegger gave birth to baby number three—a boy—on Friday, November 8.

The joint Instagram post also served as the official reveal for their son's name too, and featured his unique name against a baby blue sticker-like graphic. "We are overjoyed to announce the birth of our son, Ford Fitzgerald Schwarzenegger Pratt," the caption for the post read. "Mama and baby are doing well and Ford’s siblings are thrilled by his arrival. We feel so blessed and grateful. Love, Katherine and Chris."

Ford Fitzgerald Schwarzenegger Pratt marks the third addition to their growing family—Pratt and Schwarzenegger already share a pair of daughters, Eloise Christina, 2, and Lyla Maria, 4. The Guardians of the Galaxy actor Jack, 12, that he shares with his ex-wife, Anna Faris.

Ahead of Schwarzenegger giving birth to her and Pratt's son, the actor revealed that the couple were waiting until her delivery to find out the sex of their baby. "We don’t know!" he told Savannah Guthrie during a recent visit to the TODAY show. "I’ve got my son Jack, and then the two girls. So, we don’t know, we’ll wait. We wait and we’re surprised on the day."

Pratt kept his mouth shut about his hunches of the baby's sex, noting that he "has a feeling" about what gender the child will end up being. "I have an intuition but I won’t say what it is in case I’m wrong and then the child sees this piece and that’s confusing to them. So, one day, child, you’ll know I knew. I knew exactly who you were."
