This week’s This Is Us dropped a massive surprise on fans — but Chrissy Metz, who plays the newly-pregnant Kate Pearson on the show, revealed that not even her own family knew the big twist ahead of time.

Responding to a fan on Twitter who asked, “How hard was that to keep to yourself?” Metz replied: “Beyond difficult! My real family didn’t even have a clue.”

But, as ET learned, it wasn’t just friends and family who were in the dark about Kate’s pregnancy — the cast was, too.

Susan Kelechi Watson, who plays Randall’s wife, Beth, told ET that the relevant scenes about the shocking surprise weren’t even in the initial script. “It was one of the those things that was left out of the script when we first got it,” she said of the pregnancy reveal. “But it was such a lovely moment. When I finally did get to read the script for that scene, I could just imagine Chrissy [Metz].”

ET caught up with Milo Ventimiglia last month to see what else viewers should watch out for in season two. Check out what he had to say in the video below.

This Is Us airs Tuesdays at 9 p.m. ET/PT on NBC.
