Four years after Jon and Kate Gosselin's reality TV marriage ended in a bitter divorce, the duo are still fighting it out in court. In August, Kate blindsided her ex with a multi-million-dollar hacking, wiretapping and identity theft lawsuit, and now, Breaking Celebrity News has learned, he's hitting back with a motion to dismiss what he calls a "fishing expedition" by the mother of his eight kids.

Kate's lawsuit accused Jon and Kate tell-all author Robert Hoffman of illegally accessing her computer, email, and bank accounts. New court documents obtained by Breaking Celebrity News and filed by Jon's lawyers in Pennsylvania on October 22 lay out point by point why Jon is asking a judge to dismiss her claims against him. (Kate has already dismissed four of her eight original claims, after Jon filed an earlier motion to dismiss in September.)

DOCUMENTS: Read Jon's Motion To Dismiss The Case

First and foremost, the documents allege, Kate's complaint "consists of little more than threadbare recitals of" her accusations, and little in the way of explanation. Claiming that Kate did not provide "sufficient factual allegations to demonstrate" the truth of her claims, the documents say that her complaint "is too vague" because she did not specify which computer or online accounts were accessed, when they were accessed, or how information needed to accomplish the access was obtained. Kate's claims, the documents allege, "are pure speculation, a fishing expedition, and should be treated as such."
