The 'Pretty Woman' star - who has three-year-old twins Hazel and Phinnaeus
and a five-month-old son Henry with husband Daniel Moder - was furious after
spotting the paparazzo outside a Los Angeles school and decided to tail them
when they drove off.
Julia, 40, then pulled up alongside them on the wrong side of the road
angrily beeping her horn and forcing them to pull over.
The irate actress stormed up to the photographer's vehicle, and fumed: "So
listen, you are going to turn your camera off and I am going to talk to you
about how you were at a school where children are."
Julia is not the first celebrity to lose her cool with the paparazzi.
