The "Mean Girls" and "Freaky Friday" star was arrested at 4 a.m. and charged with third-degree assault.
She left a police precinct nearly four hours later with a black jacket pulled over her head. She was wearing leggings, a green mini skirt and high-heels, and drove off in a black SUV with a driver and another man who was seen going in and out of the precinct.
She allegedly got into the spat with another woman at Club Avenue, in Manhattan's Chelsea section. She struck the woman in face with her hand, police said. The woman did not require medical attention.
Lohan's publicist did not immediately return a call for comment.
The arrest is Lohan's latest brush with law enforcement in New York City.
