Friends of troubled Hollywood producer Jon Peters are worried about his "crazy" and "irrational" behaviour, according to his ex-wife. The SUPERMAN RETURNS moviemaker is apparently feeling the strain after being hit with a lawsuit last week (05DEC06) from a former employee accusing him of sexual harassment and exposing himself to her three-year-old daughter. He has also just completed a stint in rehab. Former wife CHRISTINE PETERS claims recent events have taken their toll on her ex, and she's trying to restrict access to her two daughters - who call Jon dad despite not being biologically related. She tells, "He's been doing a lot of crazy things and acting irrationally. "The girls didn't see him for four months and he changed all his numbers. They are spending a little time with him now because they haven't seen him. "When they were kids, Jon had the girls on the weekends. They want to spend time with him, but eventually we will go back to the old system."
