No, actress Caterina Scorsone was not pregnant in real life while filming Private Practice. The pregnancy storyline for Amelia Shepherd was written into the show, and the baby bump seen on screen was created using prosthetics and other visual effects.
Caterina Scorsone had her first child, a daughter named Eliza, in 2012, after the show had already aired for several seasons. She later welcomed her second child, a son named Arlo, in 2016.
While the pregnancy storyline for Amelia was a significant part of Private Practice, it was not based on Caterina Scorsone's real-life experiences.
