Julia Roberts gave a paparazzo a piece of her mind after he attempted to take pictures of the actress doing the school run with her young children.

The mother-of-three lost it while driving her two-year-old twins Hazel and Phinnaeus in L.A., with an overzealous snapper in pursuit.

Julia reportedly did a Clooney and forced the photographer to pull over before giving the shocked paparazzo a stern telling off.

According to TMZ, the enraged Roberts told the cameraman, "Listen, you can turn your video camera off. You're at a school where children go. Turn it off."
