The 26-year-old actress has been charged with three misdemeanors for lying to Santa Monica, Calif., police about a June car crash on the Pacific Coast Highway. The charges revolve around whether Lohan was driving the Porsche that got mangled during the accident, or if she was in the passenger seat at the time of the crash. Lohan initially said she was a passenger, police found evidence she was the driver.
More importantly, the Santa Monica charges may be enough for a judge to revoke Lohan's probation in connection with a conviction for stealing a $2,500 necklace in 2011.
This is all in addition to her fourth misdemeanor, for third-degree assault, which she racked up in New York City early this morning after allegedly hitting a woman at Club Avenue in Chelsea.
After the 4 a.m. incident, Lohan was taken to New York's 10th precinct, where she received a desk appearance ticket. She was seen leaving the station just after 7:30 a.m., with a black jacket pulled over her head.
Lohan allegedly assaulted the woman during a dispute. The actress, a regular at Avenue, was banned from the club earlier this year following an incident in which she tweeted that Justin Timberlake was seeing another woman at the club when he was dating Jessica Biel.
Lohan's publicist declined to comment, saying Lohan's attorney, Shawn Holley, is fielding requests for comment. Holley did not immediately respond to ABCNews.com.
Before going to Avenue, Lohan was spotted at Justin Bieber's concert at Madison Square Garden. A New York Times reporter who was at the show tweeted, "Lindsay Lohan just came to the row in front of me at the Bieber show, got swarmed, then turned and left."
It's been a tough week for Lohan. Her latest attempt at a comeback, the Lifetime movie "Liz & Dick," premiered Sunday to a not overwhelming audience of 3.5 million viewers. Critics almost universally panned the Elizabeth Taylor biopic.
She's also had a spate of legal troubles this fall. In September, she was arrested outside New York's Dream Downtown hotel when a pedestrian claimed she hit him with her car and did not stop. The Manhattan District Attorney's Office declined to prosecute that case.
That same month, Lohan was involved in a hotel-room quarrel that began over a set of cell phone photos of her allegedly taken by a part time Congressional aide, Christian LaBella. Lohan claimed LaBella had assaulted her, which led to his arrest, but the misdemeanor charges against him were later dropped.
In October, police were called to her Lohan's home on Long Island after a report of a fight between her and her mother. An investigation revealed "no criminality."
So far, Lohan has been imprisoned six times, but has spent less than two weeks behind bars. Last year, she spent 35 days under house arrest after pleading no contest to stealing a $2,500 necklace. She remains on informal probation for that theft, which means she doesn't have to check in with a judge or probation officer but could face a jail term if arrested.
In March, Los Angeles Superior Court Judge Stephanie Sautner took Lohan off probation from her 2007 DUI case. In court, Sautner praised Lohan for doing "everything that this court has asked of her," including completing 60 days of community service and multiple psychological counseling sessions. She also offered some advice: "Stop the nightclubbing and focus on your work."
