Jason Alexander, a former husband of Britney Spears, has publicly criticized Kevin Federline's recently released memoir, "You Thought You Knew," adding another layer of complexity to the ongoing saga surrounding the pop star. The memoir, which promises an inside look at Federline's life and his relationship with Spears, has already stirred controversy due to claims made about the singer and her involvement in the "Free Britney" movement.

Federline's assertion that the "Free Britney" movement, which aimed to end Spears' conservatorship, has "gone too far" appears to be a major point of contention. While the specifics of his argument remain unclear, it has clearly resonated negatively with those who championed the singer's freedom.

Alexander, a childhood friend of Spears who was briefly married to her in 2004, took to Instagram to voice his disapproval of Federline's book. While the full content of Alexander's post isn't detailed, the report suggests he is showing support for Spears amidst the renewed media attention. It's understood his post directly addresses the claims made within the memoir and seemingly defends Spears against Federline's portrayal.

The release of "You Thought You Knew" has reignited discussions about Spears' past and her relationships, particularly her marriage to and subsequent divorce from Federline. The former couple share two children, and their co-parenting relationship has often been a subject of public interest.

Alexander's intervention further complicates the narrative, highlighting the divided opinions surrounding Spears and her journey. With the memoir already generating significant buzz and criticism, it remains to be seen what further reactions and revelations will emerge in the coming days. The situation underscores the enduring public fascination with Britney Spears and the individuals intertwined with her life, even years after the end of her conservatorship. The full extent of Alexander's comments and their impact on the ongoing discussion are yet to be fully realized.
