The Associated Press reports that Kate, 38, claims in the federal lawsuit that Jon, 36, accessed private information for the book, Kate Gosselin: How She Fooled the World, written by Robert Hoffman, who is Jon's friend and business partner. "Jon violated a federal anti-hacking statute in order to publish salacious, scandalous and defamatory information about Kate," said Kate's lawyer A. Jordan Rushie. "It's damaged her reputation."
The lawsuit said that the 2012 book was taken off stands after two days for illegally obtaining information. The suit accuses Jon of identity theft, wiretapping and invasion of privacy.
Kate and Jon, who starred on TLC's reality series Jon & Kate Plus 8 alongside their eight children, divorced in 2009 after 10 years of marriage. Kate is seeking unspecified damages in the lawsuit.
