Kevin Federline says his sons with Britney Spears are the reason for his new memoir

Kevin Federline says concern for his two sons with Britney Spears long kept him from telling his story, and those same concerns are the reason he's telling it now that they're men. In a memoir to be released Tuesday, “You Thought You Knew,” Federline documents his difficult years as husband, ex-husband, and co-parent with Spears, who wrote her own memoir in 2023. Federline's includes some salacious stories and some potentially disturbing details about her behavior that have already made headlines.
