The 18-page lawsuit, filed in U.S. District Court in Pennsylvania on Monday, said the following:
After the couple was separated, Jon illegally hacked into Kate’s email account and her phone and bank accounts.
Jon also stole a hard drive from Kate’s house, which contained private and confidential material. Jon the gave them the contents of Kate’s email account and the hard drive, all of which were acquired illegally, to his friend and business partner, tabloid reporter Robert Hoffman.
Hoffman used the illegally acquired data to publish a defamatory book about Kate.
Hoffman’s e-book, “Kate Gosselin: How She Fooled the World,” included several unflattering bits of information about Kate.
The e-book was eventually removed from many retail sites, but the filing claims “the damage was done.” The lawsuit asks for unspecified damages as well as legal costs.
The Gosselins divorced in 2009. While an attempt was made to keep their "Jon and Kate Plus Eight" franchise going by switching to a "Kate Plus Eight" title, that series fizzled, and the TLC series was abruptly cancelled.
