Cameron Diaz doesn’t believe in regularly flush the toilet after each use. Cameron does all she can to be environmentally friendly, and believes it is a waste of water to flush every time she relieves herself. “I do follow the, ‘If it’s yellow leave it mellow, if it’s brown flush it down’ saying. I believe in that 100 percent. But there are a couple of rules. You can’t go more than two or three times, if it’s consecutive, if you’re drinking a lot of water, without flushing. But if you have coffee or something, it’s going down!” Good to know, Cameron.

The 36-year-old actress—who drives a Toyota Prius, a hybrid electric car—has been interested in green issues since she was a child, and credits her parents with making her environmentally aware. As she explained on The Tonight Show with Jay Leno, “It’s one of those things that is just a lifestyle choice. I was brought up that way so it’s something that I automatically do. I’m rigged that way.”
