Gossip Girl star Kelly Rutherford was granted a temporary restraining order against her estranged husband, Daniel Giersch, has learned.

The star, 40, claims the German entrepreneur has repeatedly harassed her and her family -- including her mother and her nanny -- according to documents filed at L.A.'s County Superior Court.

She alleges that he has followed them and "shows up unexpectedly to threaten and scare us," the order, which is in effect for 21 days, says.

"I am pleased with the court's decision in connection with the custody case, and I feel the order is in the best interest of my children," the actress told Us in a statement Friday.

Since splitting last year, the couple has been involved in a bitter custody battle over son, Hermes, 2, and daughter, Helena, 3 months.

A hearing date to review evidence is set for Oct. 15.
