Paris Hilton in More Trouble With Authorities  5/31/07

Jail-bound Paris Hilton has had another run in with the law - she's been issued with a parking ticket.

The troubled socialite was issued the fine in Los Angeles yesterday afternoon (30May07), after authorities noticed her vehicle had outstayed the allowed parking period.

Hilton - who is due to start serving her sentence on Tuesday (05Jun07) for violating the probation terms of her 2006 drink-driving arrest - was busy painting in a nearby craft store when her car was slapped with the fine by traffic cops.

Meanwhile, TMZ reports that officials at Los Angeles' Century Regional Detention Center have already started preparations for the 26-year-old's stay - they've allegedly chosen her cell mate and issued a "written protocol" detailing "when and how things should be done for her".
