In one shot to camera she brags about giving perverted sexual favors for drugs, drawling: "I get ****ed in the **** for coke."

At a party she videos a male partygoer wearing only a towel while making a sickening racist comment.

"That looks like my ******* on a bad day, after being ****ed by ten n***ers," she laughs.

Later the 25-year-old stoned beauty approaches some pals and offers them weed: "Hi bitches...I have the best pot...Let's smoke some ****ing herb right here."

In another sad tape, Paris is out of it and alone with her pet dog Prince in a hotel. "I'm smoking pot and eating burgers that are old and I'm chilling with the Prince," she slurs.

On a yacht in Ibiza she laughingly films a pal, snorting cocaine from a huge pile spread across his naked chest.

But the diaries found in the vault reveal how, in sober moments, she realizes she is off the rails.

In one entry, Paris makes a series of vows about her secret bulimia and boozing.

She writes: "Talk to someone if I feel like throwing up. Be sober-o to AA at least twice a week. Be honest with everyone even if you might get in trouble. Eat healthy."

''I'm very concerned about it. I'm shocked actually that she would participate in something like that,'' developer Robert Falor said. The video is making the rounds on the Internet and is the subject of a lawsuit by Paris Hilton.

Falor's comments offer the first signs of strain in a partnership between a developer known for sparring with associates and the 23-year-old celebrity heiress, who has become one of South Beach's most high-profile hoteliers. Though still under construction, the 95-room ''Nicky-O'' condo-hotel has won favorable mentions by Vanity Fair, People and even David Letterman.

In other news, Ron Jeremy has finally fessed up to what Page Six reported three years ago - that he, Paris Hilton and Bijou Phillips played a cheeky game of "I'll show you mine, and you show me yours" during a party at the Chateau Marmont. Hilton "asked if they could see it. I agreed only on the condition that they flash their tops. They both said yes and took me to the nearest women's bathroom."

"We squeezed into an empty stall, they pulled up their shirts, I unbuckled my pants, and after seeing my [organ], Bijou turned to Paris and wondered aloud, 'Could this be considered cheating?' "
