Lindsay Lohan's jewelry woes may have only just begun.
According to the Los Angeles Times, law enforcement officials are investigating whether Lohan tried to leave the Venice, Calif., Kamofie & Co. jewelry store with a pair of diamond earrings before she allegedly stole a $2,500 necklace. The LA Times reports that a store clerk told police about the diamond earrings incident, which was cited in a police report, but did not result in charges against Lohan.
An LAPD spokesperson declined to comment or confirm the investigation. Lohan's attorney did not immediately respond to requests for comment.
On Wednesday, Lohan was charged with felony grand theft in connection with the $2,500 gold and semi-precious stone necklace that went missing from Kamofie & Co. on Jan. 22. After the store told police the necklace was missing, an associate of Lohan's returned it. Lohan has reportedly said that her stylist borrowed the necklace and returned it to the store.
At a Wednesday court hearing, Lohan pleaded not guilty to a charge of felony grand theft, and eluded jail time. During the hearing, she received a stern warning from a judge after entering a not guilty plea.
"Miss Lohan, let me just tell you a couple things, so we have no misunderstandings," Los Angeles Superior Court Judge Keith L. Schwartz told the 24-year-old actress. "You need to follow the laws just like everybody else. Look around this room. Everybody needs to follow the law. You're no different than anyone else, so please don't push your luck."
Lohan said, "Yes, sir," when Schwartz asked if she understood him.
Schwartz continued Lohan's felony grand theft hearing to Feb. 23 and set bail at $40,000 -- $20,000 each for the felony charge and for violation of her probation stemming from her 2007 DUI case.
Lohan posted bail late Wednesday.
If convicted, Lohan could go to California state prison for up to three years. She already has been to jail three times in the past three years for DUI, drug possession and probation violations.
California criminal defense attorney Dana Cole thinks it's unlikely Lohan will serve time for the jewelry case.
"No one's cutting her any breaks," he told ABCNews.com. "It all seemed very standard. This is not a major felony case at all, I doubt she will do any jail time on this felony, it could get reduced to a misdemeanor. The question is the probation violation; that will only be dealt with after the necklace caper is resolved in one way or the other."
The Kamofie & Co. case is not the first time the star has been connected to a theft investigation.
In 2009, British police investigated the disappearance of $400,000 worth of Dior jewels from a photo shoot Lohan did with Britain's Elle magazine.
At the time, Elle released a statement exonerating Lohan, saying, "Elle has no reason to believe that Lindsay Lohan was in any way responsible."
In 2008, Lohan was sued by a college student who claimed the actress stole and wore her $12,000 mink coat.
In April 2010, Lohan was questioned by police in connection with a stolen $35,000 Rolex. The person who filed the report withdrew her complaint before police could determine if a crime had been committed.
Wednesday's charges are the latest of many clashes -- legal and otherwise -- that Lohan has racked up over the years:
Last week, Tanning Vegas filed a lawsuit against Lohan claiming that she owes the company more than $41,000 in unpaid tanning fees she racked up between 2007 and 2009. In 2009, the same company accused Lohan of stealing its formula for a spray tanning product she sold under her Sevin Nyne label.
In December, Lohan came under investigation for allegedly assaulting a staffer at the Betty Ford Clinic, where she carried out her most recent round of rehab.
Lohan lost her most high-profile job of late in November. She was slated to star in the biopic of porn star Linda Lovelace, but because of her recent troubles, the film's director switched her out for "Watchmen" actress Malin Akerman.
Lohan butted heads with E-Trade in 2010. She sued the financial services company for $100 million for a talking baby commercial that, according to her, made a mockery of her personality. The two settled in September for an undisclosed amount.
2010 wasn't exactly a banner year for Lohan: In September, she tested positive for drugs and had her second prison stint before beginning rehab at Betty Ford. She also spent part of the summer in a separate rehab program.
The real lowlight of Lohan's year probably was the 14 days she spent in prison. In July, she received a 90 day sentence for violating her 2007 probation.
This was after she missed a May probation hearing because, according to her, someone stole her passport while she was at the Cannes Film Festival. Lohan was spotted partying in France prior to coming back to Los Angeles, where a warrant was issued for her arrest. She escaped jail time but was ordered to attend weekly alcohol education classes and wear an alcohol monitoring bracelet.
It all pales in comparison to Lohan's biggest blunders yet, a set of screw ups that continue to make her life a mess. In 2007, she was arrested for two DUIs, one of which ended with police finding cocaine in her pocket. That year's infractions led to 84 minutes of jail time, multiple stints in rehab and a probation sentence with which Lohan still grapples nearly four years later.
