Paris Hilton was back in familiar territory last night ... the inside of a cop car -- only this time she wasn't a prisoner.
Hilton hooked up with the L.A. County Sheriff's Department to film some sort of PSA ... a court requirement after her cocaine bust in Las Vegas last year.
Glee star Lea Michele is sticking up for her four-legged friends that are forced into pulling carriages in major cities across the United States.
Michele, who is joining PETA in the fight against cruelty to animals, tells the animal rights organization:
"Imagine for a moment that you're forced to do hard physical labor all day, seven days a week—whether it's sweltering hot or freezing cold outside. At the end of the day, instead of relaxing on [an] easy chair or sleeping in a comfortable bed, you are locked in a tiny closet all night long."
According to PETA, these horses "are forced into dangerous traffic, where they develop respiratory ailments from inhaling exhaust fumes and debilitating leg problems from pounding the hard pavement."
