The 26-year-old actress has been ordered to appear in a New York court today, a result of her run-in with a psychic in a club back in November, reported TMZ.
She is accused of hitting Tiffany Mitchell, 28, of Palm Beach, Florida, at the trendy Avenue Lounge in Manhattan's Chelsea district.
If Lohan does not appear, an arrest warrant will be issued against her.
Lohan will appear in the court to answer a desk appearance ticket and she might get a future court date or she could enter a plea.
