Kevin Federline, former husband of pop star Britney Spears, is set to release a memoir that reveals tense details about their relationship, titled You Thought You Knew. Federline paints a picture of Spears' alleged erratic behavior throughout their marriage, stating that he remains concerned for her wellbeing.

Spears has come forward to criticize the memoir, accusing Federline of attempting to profit from their past. As the book launch approaches, differing narratives from both sides are igniting renewed media attention.

In his memoir, Federline alleges that Spears engaged in unhealthy habits while raising their two sons, mentioning instances he claims could have endangered their wellbeing. He describes a particularly chilling anecdote where their children reportedly feared her due to her behavior.

Looking back, Federline expresses regret and concern for Spears' current state, feeling that their story is moving toward a detrimental conclusion. He is quoted saying, the clock is ticking... we're getting close to the 11th hour.

Their relationship began in 2004 and swiftly led to marriage and two children, with their divorce finalized in 2007 amidst public scandal and scrutiny. Over the years, Spears has faced significant challenges, including a high-profile conservatorship that kept her under control until 2021.

In a response to Federline's assertions, Spears labeled his statements as harmful and exhausting, while asserting her love for her children and the complexity of their relationships. A representative for Spears added that this timing is yet another instance of Federline profiting from her image.

As the public eagerly anticipates Federline's memoir, both he and Spears appear to be navigating the difficult waters of their shared history and the perceptions of their lives following their separation.
