Tonight’s a party for “Mr. Darcy Broke My Heart,” a book about Jane Austen. Jane Seymour‘s the host. So, why?

“Because going back to England, Bath, that beautiful spa city steeped in history, dating to the Druids, is Jane Austen world,” said Jane Seymour. “It’s where she came to take the waters, recoup her ill health, and write ‘Sense and Sensibility’ and ‘Pride and Prejudice’ and spend much of her time. And because I lived in Bath 29 years. I know the area. Both of us Janes lived in Bath. I still vacation there, even though I’ve sold my house.”

House? Jane Seymour’s “house” was more a castle.

“Well, yes, it dated to Year 950 and was considered a national treasure. The main building had 12 bedrooms. Although I sold it, I’m still allowed to go there. My parents’ ashes are buried in the garden. The place has an amazing spiritual vibe.”

So has Seymour herself.

“I almost died at one point,” she said. “I actually felt the spirit leave the body. Although I’d already gone on, I recall looking down at myself. I could see where the syringe was, where a piece of paper was. I could actually see people resuscitating me.”

Before spiritual Jane Seymour goes on to that great big storage space in the sky, she meanwhile has a nice big one here on Earth.

“I kept the costumes from my TV series ‘Dr. Quinn, Medicine Woman.’ Props, too. They’re all in a closet. At first it was in case we got another round of shows. But now I just keep looking at them, and maybe I’ll start donating some. I actually have many mementos. Dresses from my movies and keepsakes, like what was given me by my good friends Johnny and June Carter Cash.”

To the important things. How does she keep her looks?

“I do pilates, aerobics, weights, gyrotonics. I eat organic foods. I have a skin-care line called Natural Advantage. I don’t do Botox or Restylane. What’s happening is, I’m just starting to look like an older version of me. I’m wrinkling — but slowly.

THIS week’s news about coming Su preme Court openings and that even more than one Supreme might be shuffling off to Buffalo or wherever he/she may shuffle? I am truly annoyed with you. This is not “news.” Kiddies, Mother told you this one month ago. I even told you who they’d be — Ruth Bader Ginsburg and John Paul Stevens.

Now, anyone mentioned the so far mumbled-about-only-behind-sealed-doors possibility that in this coming Supreme Court draught Our Father Who Art in the White House could . . . would . . . might . . . nominate Biden to the bench? The idea being to get Hillary as VP. To shore up his poll numbers. Let nobody say he’d even throw Michelle under the bus so’s to keep his government housing job. Let nobody say that. However, let somebody say that since his support has eroded with working-class Democrats, and that’s Hillary country . . . is all I’m saying.

OY, the frost between Nathan Lane and Bebe Neuwirth in B’way’s in coming — we hope — “Addams Fam ily” show could power your refrigerator . . . The Yankees’ World Series trophy is touring Asia. Traveling first class on its own two seats. Sitting in Row 1A and B . . . Beverly Hills Paley Center. A media discussion with types like Norman Lear, Lou Gossett, Suzanne de Passe, Mos Def. Handed a mike, Jane Fonda said: “No thanks. Don’t need it. I’m enough of a loud mouth.” . . . European powerbrokers fresh from Davos: “The old antipathy toward America is dying. Our children went to school there. They have American ways. Europe’s next generation will change everything.” . . . Prince Edward‘s missus, Sophie, got china from the shop where in 1906 Czar Nicholas replaced dishes from a 1776 set. He was subsequently assassinated. Versace bought there, too. He was assassinated, too. Better to try the Pottery Barn . . .

STAGE Deli to name sandwiches after Snooki and The Situation of “Jersey Shore.” And what’s to be in them? One’s ham, baloney and tongue. The other? “Something really cheesy.”

SHARON Stone‘s playing mama these days. Makes the breakfast, drives her kids to class daily and now hosting school parties for the grown-ups, which is causing friction. Not every parent can be invited . . . Monte’s Trattoria — sister to owner Peter Mosconi‘s Villa Mosconi (they’re both on MacDougal Street) — had a banquet party Friday night. At the table, Elisabeth Shue and brother Andrew Shue . . . Behind me Saturday night at “A Little Night Music,” a guy kept saying: “Isn’t Catherine Zeta-Jones beautiful? Isn’t she gorgeous?” Yeah, OK, she is . . . Pay attention: Real reason the Ten Commandments isn’t posted in any courthouse in the nation is that you can not post “Thou shalt not steal,” “Thou shalt not commit adultery,” “Thou shalt not lie” in a building filled with lawyers, judges, CEOs and politicians. It creates a hostile work environment.

From reader Freddie Salahi. There’s a sign on a fence around a construc tion site in Orange, NJ, that says, “Keep Out! Trespassers will be prostituted.”

Surely, only in New Jersey, kids, only in New Jersey.
