Prosecutors on Thursday charged Courtney Leigh Ames with two counts of receiving stolen property.
An amended complaint accuses Ames of wearing a necklace taken from Lohan's home to a December court hearing where she pleaded not guilty to burglarizing Hilton's home.

Robert Schwartz, Ames' attorney, says his client did wear the necklace but may not have known it was stolen. She is not charged with the August break-in at Lohan's house.
