Sexy actress Cameron Diaz could not wait to unveil the 2,386th star on the Hollywood Walk of Fame yesterday, because she likes the idea of people walking all over her. Speaking before the ceremony, the star insisted she's more excited than most to get her star. She told The Hollywood Reporter, "It will be cool to be under people's feet."It really is the place where people can understand exactly that actors are not really stars, they don't exist in the sky, they exist on the ground just like everybody else." Diaz's star is right outside the Egyptian Theatre on Hollywood Boulevard. Friends Tom Cruise and Katie Holmes also were there to help her celebrate.
