JODIE FOSTER'S WIFE FIRST JOHN HINCKLEY ... NOW THERE'S A NEW THREAT TO OUR FAMILY

Jodie Foster has a new obsessed fan -- on top of having to deal with John Hinckley Jr.'s prison release -- and the new one is tracking her everywhere she goes ... according to Jodie's wife. Her spouse, Alexandra Hedison, got a restraining order against Celine Martelleur ... who's popped up at Alex and Jodie's Bev Hills home, and also in Toronto when Jodie was filming there. Alexandra says Martelleur has repeatedly professed love for Jodie -- mostly in creepy emails, one of which said, "I am still in Toronto until next month. I am around avoiding cops. Jodie is in my thoughts every minute." In the docs, Alexandra says she was home on Dec. 9 when Martelleur buzzed at their security gate. When Alexandra asked via intercom who it was, she says Martelleur replied, "Celine, you should know who it is." She called cops, but law enforcement sources tell us officers didn't arrest Martelleur because there was no protective order. Alexandra's taken care of that -- the restraining order requires Martelleur to stay 100 yards away from Jodie, Alexandra and their 2 kids. In her docs, she refers to Jodie's history with "mentally troubled" people like Hinckley, who "shot President Ronald Reagan in 1981 based on his obsessive fixation with [Jodie]."
