On September 29, 2009 TLC announced that, as of November 3, 2009, Jon & Kate Plus 8 would undergo a name change, to simply Kate Plus 8 . Jon Gosselin would continue to appear on the show, just less frequently . However, on October 1, 2009, it was reported by People .com that Jon Gosselin has filed a legal action against TLC to prevent the show from resuming and will consider the entry of production crews into the family home as criminal trespassing . The final episode of Jon & Kate Plus 8 aired on November 23, 2009, announced by TLC three days earlier . It was announced on the June 22, 2009 episode of the show that the couple were separating, and that divorce proceedings had begun . Gosselin then began looking for a new apartment in New York City, reportedly visiting Donald Trump-owned Trump Place in Manhattan's Upper West Side . On December 18, 2009, it was announced that the couple's divorce had been finalized. Earlier in the month, Jon Gosselin's girlfriend, Hailey Glassman, announced that she broke up with Jon because she discovered during a deposition in the case against TLC that he has been unfaithful to her by having a relationship with Kate Major, a reporter for The Star tabloid. On October 15, 2009 it was announced that TLC had filed suit against Jon for allegedly violating their contract with paid and unpaid television appearances he had recently made on several media outlets. The network claims it lost more than $30,000 as a result of his alleged breach of their contract. Gosselin's attorney responded that the contract was null and void once TLC renamed the show Kate plus 8, and that in any event the contract is unenforceable because it was signed while Gosselin had no legal representation. .
