TMZ claims that Lohan's lawyer Shawn Chapman Holley has informed the star that she could be charged as early as Monday, despite previous suggestions that she would escape prosecution after the Venice-based Kamofie & Company store waited too long before reporting the incident.
If convicted, the Mean Girls actress will face a maximum of three years in jail.
Lohan has adamantly denied stealing the necklace, insisting that it had been loaned to her by the store. The trinket in question has since been returned to authorities.
