Kate Gosselin filed a civil action against ex-husband Jon Gosselin in Pennsylvania District Court on Monday, accusing him of violations of the Computer Fraud and Abuse Act.
In the documents, Kate alleges that Jon hacked into her email account, her phone and bank accounts. She also contends that he stole a hard drive from her house and gave all materials to his friend and business partner, tabloid reporter Robert Hoffman.
The documents then were used to publish a book by Hoffman titled, "Kate Gosselin: How She Fooled the World," the suit claims.
Gosselin is seeking unspecified damages, attorney's fees and an injunction on the information.
Kate Gosselin and Jon Gosselin first rose to national fame after Kate gave birth to sextuplets in 2004. The former couple subsequently starred in a television reality series, "Jon and Kate Plus 8" (later just "Kate Plus 8"), from 2007 to 2011.
