Britney Spears' ex-husband, Sam Asghari, subtly criticized Kevin Federline, Spears' previous husband, ahead of the release of Federline's memoir, "You Thought You Knew." Federline's book details his relationship with Spears and the challenges of fatherhood amidst their tumultuous marriage. Asghari sarcastically commented on Federline's book, implying it would be a guide to being a 'professional father.' Federline's memoir promises an intimate account of his experiences, including heartbreak and ridicule, while raising their two sons. The book's release comes amid Spears' claims of limited contact with her children.
