I almost feel sad for her. Here’s the story behind those new pics and videos.

As if one night in Paris wasn’t enough, you can now take an extended tour.
The sex-crazed heiress is burning up the Web again – thanks to a couple of porn purveyors who posted a treasure trove of her most embarrassing personal items – including sleazy sex tapes, topless photos, love letters, medical records and even hundreds of celebrity cellphone numbers.

Hilton had kept all of the material in a storage locker when she moved from one Los Angeles mansion to another in 2004.

When she failed to pay a measly $208 storage bill, the goods were sold to an unidentified buyer – and then obtained by “Sultan of Sleaze” David Hans Schmitt and broker Bardia Persa.

The duo launched the site – parisexposed.com – yesterday, charging $39.97 a month for access.

Paris was obviously a pack rat – saving all sorts of things. Among the random items:

Prescription bottles for Hydrocodone, a painkiller similar to OxyContin used to manage anxiety disorders, post-party sleep aid Ambien and the herpes medication Valtrex.

A medical bill from a Los Angeles clinic, billing an “Amber Taylor” – with the same birth date as Paris – for a miscarriage in March 2003.

A journal analyzing her booze-fueled dreams.

Her reality TV co-star Nicole Richie’s University of Arizona ID card.

Sister Nicky’s Nevada marriage certificate.

Several bank statements, including one with an ending monthly balance of just $9.26.

Home videos she shot of visits with her sick grandmother.

To-do lists that include an assortment of errands, including a reminder to buy Christmas gifts.

No stranger to negative publicity, Hilton is nonetheless “incredibly upset and angry” and feels “victimized” by the blatant invasion of her privacy, according to her spokesman, Eliot Mintz.

He blamed a “bureaucratic foul-up” and is threatening legal action – demanding the items be pulled from the site because it invades his client’s privacy.

“We are going to explore all of our legal options about this matter,” said Mintz. “She is enormously upset.”

Among the hours of video footage on the site is a series of short tapes of a naked Hilton being filmed by Joe Francis, the “Girls Gone Wild” creator, and her former fiancé, Jason Shaw.

Francis tapes the dazed and confused heirhead – first taking off her red bikini top on a yacht in St. Tropez, then later swooshing around in a bubble bath while he begs her to show him her body.

And she doesn’t disappoint – eventually hosing off the bubbles.

But on another tape, where Francis is not present, she calls him a “rich loser.”

Some of the items show a tender side of Paris – like when she’s lying in bed with Shaw, a chiseled Tommy Hilfiger model. She’s seen giggling, kissing him and playing with his hair.

Other videos are taped using night vision: she gets drunk and dances on banquettes with Tara Reid, and tapes a shirtless fat guy doing cocaine lines off his own belly.

In Cancun, she describes herself as “the hottest person in the world.”

Hilton also tapes rambling messages to friends while filming herself in the mirror, saying she’s too busy “smoking pot and eating burgers.”

Hilton is also obsessed with to-do lists and details her wacky errands meticulously: “Vet app’t – for teeth and wiener, send book to Ford, call Kim, make Xmas list, pick up cage from grandmas, buy a Sidekick, buy Nicky phone – and wrap it.”

Scrawled across an entire page is a reminder to “Get s-t out of car!”

Also buried in the book are cut-and-paste collages Paris created of herself – made of paparazzi shots torn from magazines.

Crumpled love letters to the heirhead from ex-fiancé Shaw are scribbled on hotel stationery and reveal intimate details of their time together.

“I could shovel s-t and be happy because I’m with you,” he writes.

“I love you. I love the way you move. I love the way you smile.”

He also writes about Paris to himself in a diary that she kept: “I am angry at Paris. She always seems to do the wrong thing. She always loses her phone. That is a reason I cannot get in touch with her. It hurts. I feel this pain inside knowing that we do not love equally.”

We also get a peek into what Hilton actually does to pass the days instead of work – there are highlighted movie scripts, directions to auditions, scheduled model shoots, appointments with interviewers and movie studios, an actors-union card, voice-lesson reminders and photo proofs of herself.

A number of ID cards – both fake and real – are in their own category.

Hilton’s California driver’s license is in there along with a fake Ohio resident card, which states she was born in 1979.

She has Nicole Richie’s University of Arizona card from her short stint in college and a credit-card-sized fake ID card labeled “Superstar” with a photo of ex- pal Britney Spears.

Hundreds of still photos of her with friends are displayed, along with a scan of the original marriage certificate of sister Nicky’s short-lived Vegas wedding to Todd Meister.

Hilton’s extensive list of friends’ phone numbers is scrawled on everything from dirty napkins to envelopes.

Among the names are Pauly Shore, Kim Stewart and George Maloof, owner of the Palms hotel in Las Vegas. But most are listed by their first names only.

I will fap to her in her honor.
