Lindsay Lohan is due at a Los Angeles court on Wednesday to face a charge of felony grand theft involving a $2,500 necklace that a jewelry store had reported missing.
The 24-year-old actress earlier this month pleaded not guilty and had said on her Twitter page that she "would never steal."
Lohan is on probation stemming from a 2007 drunk driving case. If convicted of her current felony charge, she could be sent to state prison for up to three years, which would mark her fourth stint behind bars.
Lohan has for the past few months been forced to undergo random drug and alcohol testing to ensure she has not violated her probation. Her attorney, Shawn Chapman Holley, has maintained the actress' test results have come back clean.
Lohan said on her Twitter page last week that she had not visited a Los Angeles night club, as suggested by online reports, adding: "I take my sobriety seriously. please dont believe this accusations. i know the rules and i wouldnt risk probation."
Lohan is accused of stealing the necklace from Kamofie and Co., a store located in the Venice area of Los Angeles on January 22, three weeks after she was released from court-ordered rehab.
The Los Angeles Police Department issued a search warrant on February 2 for Lohan's home to try to find the necklace. The item was returned to police before it was served.
Her lawyer has said the actress' case is "entirely defensible" but that they "will entertain a discussion concerning a plea if it means no jail so that she can move forward with her recovery and her career."
Lohan had relocated to the Venice area after she underwent treatment at the Betty Ford Center. Her rehab stint was part of a punishment handed down for violating the terms of her probation stemming from her drunk driving case.
Lohan pleaded guilty in 2007 to being under the influence of cocaine and no contest to driving with a blood-alcohol level above 0.08 percent and reckless driving.
Lohan's three stints behind bars have each lasted 84 minutes, 14 days and 15 hours - the last of which occurred in September after she failed a drug test and wrote about it on her Twitter page.
The stolen necklace case is the second active police investigation that could send Lohan to jail if a judge determines she has violated her probation.
The actress is also currently under investigation from Prosecutors in Riverside County who are considering pressing battery charges against Lohan over a December altercation the actress had with a worker at the Betty Ford Center.
