Anderson was in town to promote her new movie, "Blonde and Blonder." Earlier in the day, she had complained to AP Television News about the paparazzi, saying that Cannes was "a frenzy, it's crazy, it's silly."
"Even watching it on television this morning, seeing these people, it's like the actors are prodded through like cattle, `turn this way, turn that way,"' she said, adding that Cannes was nonetheless "quite glamorous."
The 39-year-old former "Baywatch" star had said previously that she would not attend Cannes, where her movie is screening on the sidelines of the official lineup, but later changed her mind.
"My kids come first even in my schedule," said Anderson, who has two young sons with former husband Tommy Lee. "When I schedule anything that I do, it's around their baseball games or their soccer matches or their ... everything."
In "Blonde and Blonder," Anderson co-stars with Denise Richards in what is being promoted as "Dumb & Dumber" meets "Legally Blonde."
