Drew Barrymore calls Cameron Diaz "Poo Poo".
Child star Drew and Cameron have been close pals since they were teenagers and Drew - who claims she doesn't have a lot of famous friends - revealed she still uses the unusual nickname for Cameron.
She told Marie Claire magazine: "I've never felt comfortable with this, sort of, camaraderie of famous people. I've known Poo Poo [Cameron Diaz] since I was 14 years old. We just happened to know each other before her career started, and I was working in a coffeehouse trying to refigure out my life. So in a weird way, it doesn't even count with us."
Drew - who has daughters Olive, three, and Frankie, 22 months with her husband Will Kopelman - also revealed that she leaves the glitz and glamour of Hollywood behind when she is not working.
She said: "I went to parent's night, and I wore some lipstick and concealer, and I thought the people at school looked at me kind of differently. I normally come with acne, and Ugg boots, and I thought they were like, 'Oh that's nice, she made a little bit of an effort.'"
