Rock 'n' roll ain't always pretty. In a court filing Friday, former White Stripes frontman Jack White denied threatening his estranged wife, who was recently granted a temporary restraining order. Karen Elson showed the court emails from White that show he's unhappy with her plan for their children's education, and includes a tirade against singer Dan Auerbach of The Black Keys, claiming he had "ripped off" White's music. In his filing, White denied the allegations. "The reason for filing this response is that Mr. White does not want to be portrayed as something he is not, violent to his wife or children," his attorney wrote.
