Paris 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.
And she has hired high-powered Vegas attorney David 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 this morning 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.
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 was not responding to emails.
