Masha Markova, 22, claims that the Mean Girls star took her $12,000 golden sheared mink coat when they were both at the New York City nightclub 1Oak in January, the Associated Press reports, citing papers filed in Manhattan's state Supreme Court.
Markova, a New York college student, says she was flipping through a magazine and found a photo of Lohan wearing her coat. "It was my coat. It was no doubt," she told the New York Post.
The coat reportedly was returned to her by the club in February.
There was no immediate comment from Lohan's reps on the lawsuit.
