Three other cars apparently driven by paparazzos were also pulled over near the Van Nuys Boulevard exit, but only one stayed for police questioning, AP said.
Photographer Julio A. Goncalves was cited for speeding and stopping in a non-emergency situation after pulling around the reality TV star's car and snapping photos of her, CHP Officer Ming Hsu said in a statement.
