Hilary Duff's mom went OFF on the paparazzi and I don't blame her. Apparently Hilary's mom and other daughter Haylie were coming home from Haylie's birthday celebration when they were swarmed by photographers. Nothing unusual (except they were chasing down Haylie who hasn't done much of anything ever) when her mom starts yelling and screaming at them. I totally get it though... these jerks were on the yard and in the driveway. That's not cool. They can shoot all they want from the street and sidewalk but to actually come up on the property? How rude! Not that the paps are known for having manners. In any event, the video shows you not to mess with Momma Duff!
