Nicole, 25, confessed to officers she had taken the strong painkiller
Vicodin and had smoked marijuana.

The former heroin addict has a previous DUI charge from 2002 and California
law states that a repeat offence carries the mandatory jail sentence of five
days.

The two buddies recently dined at Mr. Chow in L.A., where Richie expressed her fears to Hilton reports MSNBC

A source told Life and Style Weekly magazine: "She was really freaking out.
Paris kept telling Nicole not to worry, that everything was going to be
fine."

If convicted, Nicole would also have her driving license suspended for one
year and be ordered to attend an alcohol education program for a
year-and-a-half, even if the second conviction is not alcohol-related.

Paris recently negotiated a plea with prosecutors in her own DUI case.
The hotel heiress was charged after she was found to be over the legal
blood-alcohol level. Her excuse was that she had not eaten all day. Paris
insisted she had drunk just one margarita cocktail.

The 25-year-old pleaded not guilty to DUI, instead pleading no contest to a
lesser charge of reckless driving. Paris was placed on probation for 36
months and ordered to pay a $390 fine and attend an alcohol education
program.

Her lawyer Howard Weitzman will also represent Nicole in her DUI case.
