Cameron Diaz Hasn't Used Antiperspirant...in 20 Years!

Find out why The Other Woman actress keeps her armpits free of the beauty product

Cameron Diaz says the world would smell better if people stopped using antiperspirant.

"I don't believe in antiperspirant," the actress told me at last night's premiere of her new comedy, The Other Woman (in theaters on Friday). "It's really bad for you. I haven't used it for almost 20 years."

Really?

"You're stinky, because you use antiperspirant," Diaz said. "It keeps all the stink in."

Even men should go without? Yup!

"Let it go and just trim your armpit hair so it doesn't hold onto the scent," Diaz said.

Diaz has been all about body hair these days. Earlier this month she cleared up her views about pubic hair after advising women in her book, The Body Book, to keep their vaginas "fully dressed."

"I would like to clear up what I said. I don't care what women do with it, but we should be informed about how their bodies work," Diaz said during an appearance on The Graham Norton Show. "It [pubic hair] is there for a reason and to laser it off is to lose it forever!"

She writes in her book under a section titled In "Praise of Pubes," "I hear that there's a big fad these days of young women undergoing laser hair removal on all of their lady bits."

Diaz then warns, "I know you may think you'll be wearing the same style of shoes forever and the same style of jeans forever, but you won't. The idea that vaginas are preferable in a hairless state is a pretty recent phenomenon, and all fads change, people."
