A teenager was sentenced to 117 days in jail after pleading no contest to stalking Hilary Duff.
A Superior Court judge on Friday also ordered 18-year-old Maksim Myaskovskiy to serve five years probation.
Myaskovskiy was arrested in November after police said he made several phone calls from a hotel room to a private security firm employed by the singer-actress.
An investigator with the firm told police Myaskovskiy threatened to harm Duff at an event she was scheduled to attend, the AP says.
Duff and her family sought a protection order against Myaskovskiy on Oct. 12, alleging he tried to contact her by visiting her neighborhood, the neighborhood of her then-boyfriend - Good Charlotte singer Joel Madden - and her mother's home.
Duff, 20, is best known for starring in the long-running Disney Channel show "Lizzie McGuire."
