Jail for actress Duff's stalker

Hilary Duff is best known for her role in TV series Lizzie McGuire

A teenager who stalked and threatened singer and actress Hilary Duff has been sentenced to four months in jail.

A Californian court sentenced Maksim Myaskovskiy, 18, to 117 days in prison and five years on probation.

He was arrested in November after police said he made several phone calls from a hotel room to a private security firm employed by Duff.

An investigator with the firm told police Myaskovskiy threatened to harm Duff at an event she was due to attend.

Duff and her family also said he tried to contact the actress by visiting her neighbourhood, the neighbourhood of her then-boyfriend, Good Charlotte singer Joel Madden, and her mother's home.

Duff, 20, is best known for her role in Disney television series Lizzie McGuire.
