Audrina Patridge -- My Life Is in Danger

TMZ has learned "The Hills" star Audrina Patridge has filed for a restraining order against an overzealous male fan.

In the documents, filed yesterday in L.A. County Superior Court, Audrina's brother Mark Patridge is also requesting protection from the same man.

We're told the Patridges don't have any type of relationship with the person.

UPDATE: Audrina's lawyer tells TMZ, "The only thing we care about is Audrina's protection and safety -- LAPD's Special Victims Unit is involved in the case."
