Netflix's new hit mystery thriller limited series The Perfect Couple premiered on Sept. 5 and didn't take long to enchant viewers all the way to the peak of the streamer's most popular shows ranking. The series based on Elin Hilderbrand's book supplied us with plenty of questions: Who was the guilty party in the murder, what's Nicole Kidman's Greer hiding, and was Dakota Fanning actually pregnant in real life? It's that last one that even had folks on set wondering.

No, Dakota Fanning wasn't pregnant while filming The Perfect Couple. As Abby Winbury, the pregnant wife of Greer and Tag's oldest song Thomas, Fanning wore a super-convincing prosthetic. One scene in particular, which found Abby wearing a two-piece bathing suit by the pool, showed off the fake bump. It's such a seamless feat of prosthetic that it would fool anyone watching the series, which is obviously the point.
