Kate Gosselin says in divorce papers that her marriage to Jon is "irretrievably broken." The star of TLC's "Jon & Kate Plus 8" filed for a no-fault divorce Monday in Montgomery County Court in Pennsylvania. She said in papers that she's willing to "negotiate a fair and reasonable" settlement with her husband of 10 years.

The divorce filing was obtained Tuesday by The Associated Press. Lawyers for the couple said it contains boilerplate language common to all no-fault divorce petitions filed in Pennsylvania.

The series follows Jon and Kate Gosselin as they raise their eight young children, including 8-year-old twins and sextuplets who just turned 5.

Monday night's show, in which the couple announced their separation and divorce, drew a record audience of 10.6 million viewers.

Attorneys for both Jon and Kate Gosselin said Tuesday that the couple lived together on their Berks County compound until recently.

"They have been living 'separate and apart' just within the last week or two," said Jon's attorney, Charles Meyer, using a term from the divorce petition.

The court document does not explain what led to the split. But in a statement released to the media, Kate asserted that "Jon's activities" over the weekend had left her "no choice but to file legal procedures in order to protect myself and our children." She did not elaborate. Both Jon and Kate deny tabloid accusations that they cheated on each other.

"To be honest, I was hurt by Kate's statement about the divorce," Jon countered Tuesday in his own release. "I have always done everything I can to protect our family. This weekend, I was home with the kids for four days, just being a dad. No nannies, just the kids and me."

He added that while "emotions are running high for both of us right now," he hopes to "resolve things amicably."

The couple plan to spend equal time with their children at the $1.1 million house they moved into last year, with Kate staying elsewhere when he has custody, and Jon making other living arrangements when it's her turn, according to the statement.

Kate's lawyer, Cheryl Young, said Tuesday that the couple has already started negotiating the terms of the divorce.

Maybe Jon and Kate Gosselin are savvy business operators after all, even if what they did does reek of fraud.

The Associated Press got a hold of their divorce filing, and according to Kate, the couple has been more-or-less living apart for the last two years. The exact definition of that is always tenuous, but according to the filing, Kate makes no bones about the fact that their marriage has been anything but happy or loving for at least 24 months. The whole world knows the marriage has been a powder keg for at least the last few months, but for the last few years? What about their renewal of marriage vows in Hawaii?

If indeed the 'separate and apart' thing has been going on for two years, then it does appear that the last few television seasons of J&K+8 have been one big fraud. The clincher may be the marriage vows in Hawaii. We are now led to believe that someone - either Jon and Kate or the show's producers or all of them - cooked up the wedding vows stuff just to keep the obvious from spilling over into the public light. Well, who can blame them? They made a lot of money during the last two years and they do have eight young mouths to feed.

While the last few years of the show may have been a fraud, there really is nothing illegal about it. The only ones who may have a legal claim would be TLC, but I can't imagine that they'd actually have a claim nor would they pursue it even if they did. TLC has been making too much money off the Gosselins. And, really, there is nothing that says you can't renew your marriage vows even though you hate each other. Yet it now seems like everything was pretty well orchestrated and carefully crafted. All parties seemed to be in on the hoax, and this certainly went better than H.G. Wells' and Orson Welles' "War of the Worlds" radio broadcast; far fewer people were injured or died in this hoax.

Jon and Kate announcement spoiler: Kate's brother, sister-in-law confirm divorce plans

That's right -- the over-hyped mysterious "John & Kate Plus 8" announcement slated to air Monday barely lasted to the weekend.

In an exclusive two-part video released by RadarOnline, Kate's brother Kevin Kreider and wife Jodi reveal some of their personal insight to the situation. Right off the bat, Kevin confirms the couple's plans to divorce.

"Six months ago Kate came to Jon and said, 'Hey, it's over.'"

I suppose it can't really come as too much of a shock with all the recent buzz of infidelity from both parties. Plus, in my five-episode experience of watching J&K+8, it was painfully obvious that the couple's marriage was tense, to say the least.

The Kreiders also revealed how the tension created by Jon and Kate often encompassed those around them. The Kreiders have appeared in past seasons of the show, but had a fallout over a year ago after Kate threw a hissyfit when TLC planned to compensate her brother and sister-in-law.

"They would fight so incredibly much, the film crew would have a hard time getting 15 minutes of decent footage out of eight hours of filming," says Kevin. "It was horrible. Some of the production crew came to us at how they had moral problems with how they acted."

"What they were filming," adds Jodi.

In the second part of the video, Kevin reveals that Kate stated wanting no type of marriage counseling. That tidbit, combined with the fact that it was she who approached Jon saying "It's over," doesn't exactly show a great deal of commitment on her part. I mean, aren't marriages supposed to be about working things out, for better for worse, in sickness and in health, and all that?

In addition to this announcement, the video also verifies how incredibly unrealistic the show portrays the Gosselin household.

"Kate portrays, in the show, to be an incredible cook, an incredible baker, an incredible housewife," says Kevin. "I don't think, that when it comes down to daily life, she does any of those things on a regular basis."

Jodi agrees, adding a possibly veiled jab at Kate for placing her personal promotions over her family's well-being.

"It takes an incredible amount of people to pull off what they're pulling off. Having people, you know, folding their laundry, cleaning their house, doing all of your mothering jobs that all of us as mothers just do," she says. "Logically when you think about it there's no way that she could be doing all of these things and also being on book tours, writing books and speaking at churches in different places and also promoting the show."
