Booked: Paris Hilton has been arrested in Las Vegas over possession of cocaine.

She's used to posing endlessly for photographers everywhere she goes.

And it looks as if Paris Hilton has even mugshot poses down to a fine art.

Judging by her newly-released mugshot from early Saturday morning's drug arrest, all the primping and preening she did on Friday paid off.

Busted: Paris' boyfriend Cy Waits was booked for a DUI

Paris Hilton's attorney David Chesnoff has asked people not to judge the heiress for her drug arrest until all the facts are known.

'Paris Hilton was released this morning on her own recognizance,' he said today.

'This matter will be dealt with in the courts not in the media and I encourage people not to rush to judgement until all of the facts have been dealt with in a court of law. There will be no interviews and no more comments at this time.'

Hilton is denying the cocaine allegedly found in her car in Las Vegas last night is hers.

It is the same defence she successfully used when facing drug charges in South Africa last month.

Hilton insists the purse in which the drugs were allegedly found by police doesn't belong to her, sources close to Hilton have told celebrity website TMZ.

The actress was first arrested and charged in 2006 for driving under the influence and ended up having her license suspended. She was pulled over twice in 2007 and found to be driving with an invalid license.

And she has hired high-powered Vegas lawyer Chesnoff to handle the case.

Although Hilton was the only woman in the car that was stopped, she had been partying earlier at a club where her purse could have been mixed up with someone else's, says TMZ.

Hilton was arrested for possessing cocaine after her car was stopped by police in Las Vegas.

Her boyfriend Cy Waits, who was driving the car, was booked on charges of DUI.

The socialite was booked into the Clark County Detention Center early on Saturday on a charge of possession of cocaine.

And she was released at around 2.30 am local time on Saturday.

Police say she was in a car driven by a friend that was stopped when officers noticed what they suspected to be marijuana smoke coming from it.

During the stop officers found what appeared to be a controlled substance on Hilton and tests showed that it was cocaine. It is not clear how much of the drug was found.

Police spokesman Marcus Martin described events leading up to Hilton's arrest.
'Officers noticed a vehicle leaving a smoke trail of a contolled substance (and) made a stop based on that,' he said.

He did not know how much cocaine had been found.

Hilton was quickly recognised by passers-by and a crowd gathered around the area where the vehicle had been pulled over.

Calm before the storm: Paris Hilton gets primped and pampered in Las Vegas on the day of her arrest

Four years ago the reality TV star was arrested for driving under the influence of alcohol and sentenced to 45 days in prison.

She ended up spending 23 days in jail in June 2007.

On her release, she told Larry King that the experience caused her to re-evaluate the role partying played in her life.

She said she wanted 'to help raise money for kids and for breast cancer and multiple sclerosis.'

The heiress was arrested again this summer after the Brazil-Netherlands World Cup match in Port Elizabeth, South Africa, on suspicion of possession of marijuana. The case was then dropped at a midnight court hearing.

Hilton's manager was not available for comment today. Her publicist Dawn Miller referred Mail Online to the statement by Hilton's lawyer.
