Cameron Diaz learnt the perfect breast should be able to fit inside a "champagne glass" from her mother and insists big doesn't mean best.
The actress is adamant it isn't important to have large boobs and says she has always been happy with her modest chest.
She said: "I have to admit that I like my breasts to be firm and pert. My mother always told me that the perfect breast fits into a champagne glass. I found that cool and was happy that my breast stayed small ... Many women think you need large breasts, but I'm the living proof that you can go far with small ones."
Although she is happy with her bust, Cameron would never rule out having a boob job if she ever felt her breasts needed an article boost.
Speaking about whether she'd ever go under the knife to improve her assets, she told German magazine TV Movie: "So far I'm quite happy with what I have. It's not that much but I have some really effective push up bras. But I would never say never, of course. Maybe one day, if I don't like them anymore."
In her new movie 'Bad Teacher', the 38-year-old actress plays Elizabeth Halsey, a lazy educator whose main ambition in life is to marry a rich man and wants to get a breast enlargement operation to increase her chances.
