Jeffrey Francis Ausley applied for a protection order amid claims the 29-year-old 'Entourage' star turned up at his home and tried to move in.
Court documents also contain allegations she threatened him after their relationship ended. A judge has now approved the order, which means Dziena cannot go within 100 yards (300 feet) of Ausley, according to TMZ.
Dziena is no stranger to drama - she requested a restraining order against her own parents in 2011, but the motion was dismissed by a judge due to lack of evidence.
