In the filings, John Hobbs is accused of harassing Hannigan, 38, on the Internet via Facebook and MySpace posts.

The papers go on to claim that Hobbs is "mentally unstable and was recently discharged from a mental hospital," requesting that he remain at least 100 yards away from Hannigan, her husband Alexis Denisof, 46, and their children Satyana, 3, and Keeva, 1.

A judge is set to determine whether or not the order should be made permanent during a March 6 hearing.
