Richie: 'Paris was treated unfairly'

The Simple Life star Nicole Richie has spoken out to defend her jail-bound pal Paris Hilton, insisting the hotel heiress' impending prison sentence was "really unfair".

Hilton has to report to Los Angeles' Century Regional Detention Center by June 5 to start serving her sentence for violating her probation following her 2006 drink-driving arrest.
