For the past 23 years, MAC's Viva Glam campaign has been one of the brand's most beloved creations. It's raised hundreds of millions of dollars for HIV/AIDS-awareness charities and has been fronted by some of the world's most notable faces including Rihanna, Ariana Grande, Nicki Minaj, Elton John, and many more.

The brand just announced the next face of its historic campaign — and it's already getting that person is a lot of trouble.

Sia is the latest face of MAC Cosmetics' Viva Glam campaign, and her fans wish she wasn't.

Because Sia is well known for her stance on animal rights and for being vegan.

Meanwhile, MAC Cosmetics sells products in China, which legally requires cosmetic testing on animals.

A little bit of context for you: MAC itself does not perform cosmetic tests on animals. However, people in the vegan and cruelty-free communities prefer to avoid brands who actively choose to expand to China, where government animal testing is 100% guaranteed to happen.

That's why NARS Cosmetics got flamed by animal rights activists earlier this year when it announced it would start selling its products in Chinese retailers.

And it's making things rather difficult for Sia's fans, many of whom only support vegan and cruelty-free brands.

For some, it seems entirely out of Sia's character for her to support a brand with ties to China and animal testing — they question if she's even aware of the situation.

Others are just plain fed up.

Sia issued this statement defending the collaboration and linked to MAC's animal testing guidelines.

But that just seemed to make things worse.

Because Sia can't singlehandedly prevent her lipstick being sold — and animal tested — in China.

As for the fans who aren't concerned about animal testing, they're pretty damn stoked.

But everyone else...

Are these criticisms warranted? Clearly, Sia thinks not.
