Paris Hilton has been charged with felony cocaine possession following her weekend arrest in Las Vegas. If convicted, the heiress, 29, faces up to four years behind bars.

According to the police report, the officer who stopped Hilton and her pals on the famed Las Vegas Strip Friday night smelled "the strong odor of marijuana coming from the vehicle."

Upon being stopped, Hilton tried to roll up the window.

As a crowd of 100 people began to gather around, Hilton said she was "extremely embarrassed" and asked if she could go to the bathroom at a nearby hotel, the report states.

There, she asked to put on lip balm. As she began to open her purse, the officer writes, "I saw a small bindle of what I believed to be cocaine in a clear baggie begin to fall from the purse and into my hand."

The purse also contained cigarette wrappers commonly used for marijuana and a broken tablet of Albuterol.

Hilton admitted the Albuterol belonged to her -- as well as the $1,300 in cash in the purse -- but denied that the cocaine -- .8 grams, to be exact -- and the purse were hers.

When the officer asked her about the cocaine, Hilton "said she had not seen it, but now thought it was gum," according to the report.

On Saturday, Hilton's attorney said the "matter will be dealt with in the courts, not in the media, and I encourage people not to rush to judgment until all of the facts have been dealt with in a court of law."

Hilton returned to Twitter late Sunday, telling fans: "I'm so thankful to all my fans for all the love and support you are giving me."
