Paris Hilton Pleads Guilty to Cocaine Possession, Lindsay Lohan Fails a Drug Test

Paris Hilton, in a low-cut black and white dress, pled guilty to cocaine possession at the Clark County Regional Justice Center in Las Vegas, Nevada. The heiress got quite the tongue-lashing from the judge.

"I assure you that if you violate the terms of your probation, you will serve one year. Treat this very seriously, you understand me?" said Las Vegas Justice of the Peace Joe Bonaventure.

"Yes, your honor. I promise," said Hilton.

Hilton was arrested on August 27 inside a Wynn resort after a small bag of cocaine fell out of her Chanel purse.

The socialite made a deal with prosecutors, agreeing to plead guilty to drug possession and obstructing an officer in exchange for no jail time...if she stays out of trouble for a year.

"The Clark County Detention Center is not the Waldorf-Astoria," Bonaventure informed Hilton.

Hilton must also complete a drug abuse program and serve 200 hours of community service.

And another Hollywood bad girl, Lindsay Lohan, arrived at an AA meeting in Los Angeles over the weekend with a smile, despite having admitted that she'd failed a   drug test. Lindsay tweeted at 10:45 p.m. on September 17: "Regrettably, I did in fact fail my most recent drug test and if I am asked, I am prepared to appear before judge Fox next week as a result."

Right after making the Twitter confession, Lohan headed to a late-night dinner with friends in Hollywood, where she was reportedly spotted "sneaking sips from their drinks." Lohan had this to say on Twitter about her addiction problems: "Substance abuse is a disease, which unfortunately doesn't go away over night. I am working hard to overcome it and am taking positive steps forward every day."

Lohan reportedly tested positive for both cocaine and amphetamines. The judge presiding over her case had promised to put her in jail for 30 days if she tests positive for drugs or alcohol.
