Paris Jackson has been growing her armpit hair for two months and “so many people are mad about it”.

“I didn’t realise that people were going to get so upset over my armpit hair,” the 18-year-old shared on her Instagram story yesterday. “I didn’t realise that was such an issue. It is so funny.”

And an "issue" it apparently is.

No matter that Jackson speaks out for human rights and environmental issues and water conservation, the fact she's growing her armpit hair has people messaging her in disbelief and threatening to "unfollow" her .

"People are really mad," she continued. "I wish I could post some of these responses. You can just tell how angry and infuriated these people are..."

Paris Jackson really just posted her armpit hair on IG story, yeah, that was your last straw anyway, gotta unfollow

Unpopular opinion but those armpit hair photos are getting tired and desperate. Take a nap.

Jackson doesn't stop there.

"I love hair, and sweat, and BO. I f*cking love it, I think it’s great," Jackson said. "Some people think that it’s like super disgusting, especially on girls, but every human body does it. It’s natural. Get over it."

"Two months," she continued. "It took me two months to grow that sh*t. It’s not a lot, it’s really not, but I’m f*cking proud of it. Really proud. And so many people are so mad."

Thankfully, Jackson has received support from followers applauding her for doing exactly what she pleases with her own body.
