Prosecutors in Santa Monica charged Lohan with three misdemeanors related to a June accident. Hours earlier, the actress was arrested and charged with third-degree assault after a woman was punched in a New York City nightclub.
The California charges came about six months after Lohan's Porsche crashed into the back of a dump truck. She told police her assistant was driving, but detectives now believe the actress was behind the wheel as she headed to a movie set.
In that case, Lohan, 26, was charged with lying to police, reckless driving and obstructing a police officer from performing duties.
Lohan's attorney, Shawn Holley, did not return messages seeking comment.
The charges could trigger another probation violation for Lohan, who was ordered to remain out of trouble when she was released from supervised probation in March after being convicted of the misdemeanor theft of a necklace and two DUI charges.
Since then she has been arrested twice in New York, crashed her car on Pacific Coast Highway, been treated by paramedics in her hotel room, and gotten in an argument with her mother that prompted a 911 call.
None of the events are likely what the clearly relieved actress anticipated in March when she thanked Superior Court Judge Stephanie Sautner, who warned the actress that she could face up to 245 days in jail if she violated her probation again.
"You need to live your life in a more mature way, stop the nightclubbing and focus on your work," Sautner said.
In recent years, Lohan has been sentenced to the Los Angeles-area women's jail five times. Most of her stays have been short due to overcrowding, and she was allowed to serve 35 days on house arrest in 2011.
Lately, Lohan has been filming two movies and doing a cameo in the latest installment of the "Scary Movie" franchise. The first film, "Liz & Dick," premiered Sunday night on Lifetime to mostly negative reviews.
She was on her way to shoot scenes for "Liz & Dick" in June when her Porsche crashed into the dump truck and the actress was briefly hospitalized. A week later, paramedics were summoned to her hotel room. Her then-publicist Steve Honig attributed the health scare to exhaustion and dehydration.
Lohan relocated to New York after finishing her work on "Liz and Dick" and a Bret Easton Ellis film called "The Canyons" was complete.
Her arrest at 4 a.m. EST Thursday was the latest by New York police since September, when a man accused her of hitting him with her car. Prosecutors did not pursue charges.
The following month, police were called to Lohan's childhood home on Long Island after a report of a fight between her and her mother. An investigation revealed what authorities called "no criminality."
On Thursday, police said Lohan got into a spat with another woman at Club Avenue in the Chelsea area of Manhattan. The woman was punched in the face and did not require medical attention.
It remains unclear when Lohan will return to Los Angeles. No court date was announced for the crash-related charges.
People charged with misdemeanors in California can generally avoid court appearances if they have an attorney, but Lohan would have to be present for a probation violation hearing.
