Kevin Federline has announced his upcoming memoir, You Thought You Knew, which is set to be released on October 21. The book promises to deliver the story of fame, fatherhood, and the private cost of public life from one of pop culture’s most misunderstood figures. In a response to the news, Sam Asghari quipped that Federline was “a professional father” when sharing his thoughts with TMZ on August 16. This comment seems to imply that Federline is throwing shade at Asghari by comparing him unfavorably as a father figure in his memoir.
