Julia Roberts drove on the wrong side of the road in Los Angeles Wednesday, honking her horn as she chased down a photographer who tried to take pictures of her children, allegedly near a school, TMZ.com reported.

A furious Roberts got out of her car and scolded the paparazzo, demanding that he turn off his camera — and he nervously obliged, TMZ said.

"Turn it off," the 40-year-old Oscar-winner tells the photographer. "I want to talk to you about the fact that you're at a school where children go. Turn it off."
