REPORT: Jon and Kate File Separation Papers in Pennsylvania Court

As Jon and Kate’s big announcement draws near, People.com reported that the reality show couple filed documents to initiate a legal split at the Bucks County Courthouse in Reading, Pa., Monday afternoon.

Fans of the Gosselin's reality show "Jon and Kate Plus Eight" were expecting the announcement of a "major decision" on the show Monday night, after months of infidelity rumors, accusations child-exploitation and he-said, she-said accounts of which party is at fault.

TLC wouldn't comment on what the news would be from these parents of 8-year-old twins and 5-year-old sextuplets. But viewers who have witnessed the Gosselins' marriage coming unraveled are clearly welcome to draw their own conclusions leading up to tonight's episode. And to show up in droves to see it. The show is scheduled to air Monday at 9 p.m. EDT.

In a promo for Monday’s episode, a teary-eyed Kate admitted that the couple had been dealing “with this for a long time.”

Jon added, “It just got worse and worse and worse … and with all the tabloids and all that, it just made it even worse.”

Peace seems to have been in short supply for the Gosselins of late. Splashed across Web sites and magazine covers in recent weeks are accounts of infidelity by both spouses — Jon with a 23-year-old schoolteacher and Kate with her bodyguard — accusations both of them deny.

Meanwhile, their on-screen relationship has been arms-length at best.

"Very swiftly, we turned into two different people," Kate said on the fifth-season premiere last month, which attracted nearly 10 million viewers. Subsequent episodes have had less than half that viewership.

She described how she has grown apart from her husband of 10 years, saying, "it's just hard."

Last week, Jon was spotted looking for an apartment in New York City. After photographers snapped him playing with his kids Sunday, he gave an impromptu press conference on the front lawn of his Pennsylvania home, saying he had "no idea" where his wife was.

According to MyFOXPhilly, Kate has been in hiding before the big announcement.

Adding to the strain, Pennsylvania's Labor Department has opened an investigation into whether the show's production is complying with state child labor laws. TLC has said it "fully complies" with state laws and regulations.

Originally envisioned as a series chronicling the challenges of raising a supersize family, "Jon & Kate" has become more of a show that raised the question: Can this marriage be saved?

Now TLC is teasing viewers into wondering if the answer could be "no."
