Ever since Cameron Diaz’s Body Book came out, she has been making one strange statement after another. First, she urged her readers to keep their vaginas “fully dressed” and not laser away their pubic hair.

“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,” The Other Woman star later clarified. “It [pubic hair] is there for a reason and to laser it off is to lose it forever!”

Cameron Diaz has also made headlines for her bizarre theories on relationships. First, she claimed that everyone will get cheated on at some point in their lives. And then she revealed that she does not believe in monogamy.

“A lot of people chase after it because they’ve been told, ‘This equals happiness,’the actress said of monogamy. “They chase it, they get it, and then they find out, ‘Why did I think this was going to make me happy? I’m miserable.’”

But just when we thought Cameron Diaz’s comments could not get any weirder, she shocked us once again. Earlier this week, she admitted that she does not believe in deodorant. Surprisingly, she is not the only star in Hollywood who feels this way. Here are five stars who do not wear antiperspirant.

1. Cameron Diaz

Cameron Diaz Cameron Diaz actually thinks antiperspirant makes her smellier.

Not only does Cameron Diaz not wear deodorant, but she actually thinks it makes her smell worse.

“I don’t believe in antiperspirant,” Diaz told E! News. “It’s really bad for you. I haven’t used it for almost 20 years. You’re stinky, because you use antiperspirant. It keeps all the stink in. Let it go and just trim your armpit hair so it doesn't hold onto the scent.”

2. Julia Roberts

Julia Roberts Julia Roberts does not like to talk about her aversion to deodorant, and we cannot exactly blame her.

Apparently you don’t need to wear deodorant to become an A-list actress.

 “I don’t actually use deodorant,” Julia Roberts told Oprah Winfrey in 2008. “I don’t like to share that with a lot of people. It’s just never been my thing.”

3. Joan Rivers

Joan Rivers Joan Rivers thinks vodka is more effective than deodorant.

We may trust Joan Rivers’ opinions on fashion, but we think her idea for deodorant replacement is a bit hard to swallow.

“I always spray my costumes with vodka and water,” Rivers told Page Six in 2011. “It’s an old Broadway trick — two-thirds water and one-third vodka, spray your armpits and you’ll never smell again.”

4. Bradley Cooper

Bradley Cooper Bradley Cooper will not even wear cologne to cover up his body odor.

Bradley Cooper may look like a heartthrob, but he does not always smell sexy. He told Esquire in 2011 that he does not wear deodorant or cologne.

5. Matthew McConaughey

Matthew McConaughey Spirit Awards Matthew McConaughey just takes a shower if he gets too smelly.

Speaking of heartthrobs, Matthew McConaughey admitted in 2009 that he also does not like antiperspirant. But unlike Cameron Diaz, his aversion to deodorant has nothing to do with whether or not it works.

“I don’t like to smell like someone or something else,” he told People. “Just like I don’t want a big name on the back of my jeans or a big label on my jacket. If [my smell] starts to bother someone, I'll take a shower.”
