Los Angeles, California - A new source reveals the reason why childhood stars Ariana Grande, Jamie Lynn Spears, and Amanda Bynes have stayed silent on the disturbing docuseries.

The docuseries Quiet on Set: The Dark Side of Kids TV exposed a disturbing side of Nickelodeon.

Allegations came forward of inappropriate behavior by former showrunner Dan Schneider.

While the project featured raw accounts from stars like Drake Bell and Alexa Nikolas, three familiar faces were noticeably absent: Ariana, Jamie, and Amanda.

All three actresses declined to participate in the documentary because they weren't ready to visit that chapter of their lives, per OK! Magazine.

"They weren't surprised by any of the allegations," an inside source revealed, continuing, "They all turned it down. It wasn't something they were ready to discuss."

The source claims Ari knows what "really" happened and that she will discuss it when she's ready.

The silence of the three actors doesn't diminish the seriousness of the allegations against Schneider but rather highlights the importance of respecting the boundaries and choices of those who aren't ready to dive into their past.
