Izabella Miko -- one of the smoking hot bartenders in "Coyote Ugly" -- claims a pervy fan has been stalking her and posting sexual messages to her on Twitter ... and now she fears for her life.
According to docs filed recently in L.A. County Superior Court -- obtained by TMZ -- some guy named Patryk Zubrowski has been stalking Miko across the country for the past year -- from L.A. to Vegas to New York -- and even the Virgin Islands ... where he allegedly tried to propose to her.
Miko claims Zubrowski seriously upped the creep factor by sending her sexually explicit messages on Twitter ... including, "my f**king sausage is burning in my pants" ... and several more referring to the state of his member.
The scary part -- Miko played the murdered victim of a stalker on "Deadwood" back in 2005 ... and according to the docs, she's afraid Zubrowski might be inspired to reenact the gruesome episode in real life ... including the grisly ending.
Miko is asking the court to keep Zubrowski at least 100 yards away from her at all times. Attempts to reach Zubrowski have been unsuccessful.
