EXCLUSIVE
Paris Hilton has an obsessed fan who seems to be as loaded as he is angry, because he bought her an amazing classic Cadillac, and when she refused it someone mysteriously trashed the whip.
The guy -- whose first name is Johnny -- delivered the Caddy to Paris' Bev Hills gated community on Oscar Sunday. We're told the guard at the front gate called Paris and described Johnny and Paris said she was calling the cops because he's been harassing her for years.
The car sat on the street for 2 days, and on Tuesday someone bashed in all the windows. Paris is convinced Johnny's the culprit because she wouldn't accept the gift, complete with flowers in the backseat.
Law enforcement sources say they've been on Johnny for a long time. He once flew a plane over the Hilton's Malibu compound with 2 signs, one of which read, "Can't Get Paris Whitney Hilton Out of My Mind." The other read, "Mr. & Mrs. Hilton, may I court your daughter Paris?"
Johnny also once sent Paris a really expensive wedding dress in the mail with a card that read, "Will you marry me."
As for the Caddy, it's still sitting on the street because it's legally parked and registered to Johnny.
