The female genitalia is the most integral part of a woman's anatomy, Hollywood actress Cameron Diaz told talk show host Chelsea Handler to promote her latest self-help book titled The Body Book.

In an appearance at E!'s Chelsea Lately on Monday, the 41-year-old celebrity declared herself a science nerd to explain her quest for knowledge about how the human body works.

She compared the vagina to a beautiful and delicate flower that must be nourished by watering and fertilising it.

"It needs nourishment ... It's hungry," Diaz said.

She urged women to grab a mirror and look at their genitals. "Get in there ... learn about it," she said.

As for the pubic hair covering the vagina, she said it has a purpose that's why it shouldn't be permanently shaved. "I also suggest that no matter how you enjoy grooming it throughout your life - whether it's shave it all off, wax it all off, put a bull's eye, birthday cake. I don't care - just, girls, think about not taking it all off forever. Permanency means forever," Diaz said.

This is not the first time that Cameron tackled the subject of pubic hair. A year ago, she shared an anecdote about a hirsute friend with host Graham Norton and fellow guest Rod Stewart.

"It doesn't come back. You might change your mind in a few years," she warned.

The star of the next-generation Charlie's Angels also tackled other health issues such as the dangers of habitual smoking and sugar-free soda. Cameron said that lighting up one cigarette occasionally would not kill a person, she dissed drinks that claim to have no sugar content.

Someone posted the video of the show on YouTube, but the video sharing site removed it over copyright issues. The one who initially posted the clip instead provided a link below for the full video.
