She is one of Hollywood's highest-paid actresses, but Cameron Diaz once dreamed of working with animals. "I wanted to be a zoologist, to study the sociology of animals," Cameron tells W magazine. "But that's pretty much what I do now anyway. I though I'd be on the plains of Africa watching lions, but instead I'm in Hollywood watching train wrecks. I'm just kidding!" As for her current ambitions, the actress says she wants to "just kind of [take] more time getting to know myself. It sounds so corny... but there comes a time when you really have to get to know who you are... I've just been figuring out what interests me and spending time with people who are important to me and being present in my own life." And for Cam, being present might just include hitting the gaming tables and clubs of Sin City. "I loooove Vegas. It's such an easy trip from LA, and there's always a hotel room because there's about a billion of them," she laughs. "But honestly, you don't even really need one if you're just going for the weekend!"
