Red Alert at Paris Hilton's House

Cops just paid a visit to Paris Hilton's pad, to make sure she wasn't a burglary victim twice over.

We've learned the LAPD pulled a car over near the home where Paris Hilton and BF Doug Reinhardt live ... and the officers noticed Paris' gate was open. With the whole Hollywood Hills Burglar Bunch string of celeb break-ins, cops wanted to make sure history didn't repeat itself.

We're told police went up Paris' driveway, went into the yard and spoke with someone inside to make sure things were ok.

They were, and police just left the scene.
