NEW YORK (CNN) -- Hollywood starlet Jennifer Love Hewitt recently obtained a restraining order against a man who she claims had been stalking her since 2007.

The man sent hundreds of threatening letters, as well as plane tickets to Australia, and he left flowers at the home of Hewitt's mother.

Uma Thurman had even more frightening brushes with her stalker before he was convicted. Jack Jordan visited her house and also tried to get into her on-set trailer.

Thurman eventually faced Jordan in court, where he was convicted of stalking and aggravated harassment and sentenced to three years probation and psychiatric counseling. This, to me, sounds like a victory for Jordan, since he was placed in the same courtroom as his victim and could eventually go right back to stalking.

Many assume this type of thing is relegated only to those who grace the covers of gossip magazines and movie posters. Sheila Ann Grayson wasn't famous, but that didn't save her. Police in South Carolina say Grayson was killed by her stalker last May, two weeks after taking out a restraining order against him.

A new study published this month by the Department of Justice's Bureau of Justice Statistics estimated based on a survey that 3.4 million Americans per year are victims of stalking. For some perspective, that's more than the entire population of Chicago, Illinois.
