Hollywood icon Julia Roberts angrily gave chase to a car carrying paparazzi photographers after spotting them filming her near a school, reports said Thursday.

The actress raced after the photographers in her Mercedes sports utility vehicle, blasting them with her horn and gesturing the lensmen to pull over, in footage broadcast by syndicated television show "Inside Edition."

The 40-year-old Oscar-winning star of "Pretty Woman" and "Erin Brockovich" then angrily scolds the photographers for allegedly filming her near a school, ordering them to turn off a video camera filming her.

"Turn it off," Roberts tells the photographers. "I want to talk to you about the fact that you're at a school where children go. Turn it off."

The incident is the latest flashpoint involving celebrities and members of the Los Angeles paparazzi.

Actor George Clooney last week hit out at paparazzi "bounty-hunters," accusing them of risking the safety of innocent bystanders in their pursuit of celebrity photos.

Clooney, who was also involved in a filmed altercation with photographers earlier this month, said paparazzi often broke the law while chasing their targets.

"What they're doing is illegal, it's high-speed chases and they're competing with each other," Clooney said.

"They're not trying to catch me doing something stupid; they're trying to create me doing something stupid. You don't get to break all these laws and then say, 'I'm just doing my job.'"
