Overview

• Pre‑publication excerpts from Kevin Federline’s You Thought You Knew describe claims that Spears stood silently in a doorway holding a knife while their sons slept and that the boys were afraid to visit her.
• Federline writes that the situation around Spears feels as if it is rushing toward something irreversible and warns that something bad will happen if nothing changes.
• Major outlets including the New York Times and People have published or cited the excerpts, with the memoir scheduled for release on October 21, 2025.
• Spears’ representative publicly rejects the portrayals, accusing Federline of profiting off her name and stressing that Spears’ priority is the wellbeing of sons Sean Preston and Jayden James.
• The book also includes other personal claims, such as a phone call to Justin Timberlake the night before the 2004 wedding and an alleged same‑sex encounter in Amsterdam, all attributed to Federline’s account.
