LOS ANGELES (CBS) — Is Lindsay Lohan the target of a conspiracy by a shadowy group to assassinate her or is it just a case of celebrity paranoia?

The troubled tabloid star and actress posted a low-resolution photo of a man she called a “freemason stalker” on her Twitter page.

“This is the freemason stalker that has been threatening to kill me- while he is TRESPASSING!” Lohan wrote. “im actually scared now- the blood in the ‘cults’ book was too much.”

“All my fans, my supporters, please stand by me,” she added.

An apparent screenshot from one of Lohan’s security cameras shows a heavy-set man with dark hair, and a goatee, wearing sunglasses and a button-up shirt as he walks through a garden-like backdrop.

The New York Daily News reported that while a source with knowledge of the situation confirmed the alleged stalker threat is real, no explanation of Lohan’s bizarre references to either Freemasonry or “the blood in the ‘cults’ book” was given.

A longtime subject of alternative history buffs and conspiracy theorists, Freemasonry is a mysterious and apparently powerful secret society depicted recently in movies like “The Da Vinci Code” and “National Treasure” along with dozens of classic films.
