Kesha loves her Animals, but her first love are literal animals -- and as an outspoken animal activist, she's speaking out against animal testing.

Celebrating the European Union's ban on cosmetics testing on animals, Kesha penned an open letter urging other nations to join the ranks of eliminating the practice altogether.

The campaign is part of Kesha's work as the first ever Humane Society Global Ambassador, a cause that's also manifested itself into raising awareness about street dogsseal and lion hunting, shark finning, dogfighting and cruelty-free cosmetics, among others and a faux fur line to discourage wearing the real thing.

“Today I am celebrating something wonderful, something compassionate and selfless that combines two of my great loves: cosmetics and animals," K-Dollar Sign wrote. "Today, the European Union showed animal testing for beauty products the door by banning the sale of cruel cosmetics. From today, any new beauty product or ingredient that has been dripped in a rabbit’s eyes, spread on a guinea pig’s delicate skin or force fed to any animal, will not be welcome on shop shelves in the E.U.”

The descriptions Kesha uses drive the point home and help the reader visualize just what goes into animal testing -- it sounds a lot scarier in detail, right?

“To care so deeply about the suffering of animals so very far away, demonstrates something beautiful about the human spirit," Kesha continued. "So that’s why I’m writing this open letter to the global cosmetics industry, because beauty is supposed to symbolize something wonderful and pure and transformational; something that inspires us and makes us happy."

Indeed, glitter and blue lipstick bring the girl joy -- but not when they're smeared on a lab rat first.

“None of those things are true of animal testing. Animal testing is ugly -- period," she fumed. "There can be no better time than this for the cosmetics industry to walk away from animal testing; no better moment than now, when the world’s largest cosmetics market has refused to sell cruelly-produced products. This is your moment to make the world a better, kinder, more beautiful place. Take it," she urged. "Join with Humane Society International’s Be Cruelty-Free campaign to create a world where no animal has to suffer and die for the sake of cosmetics.”

Work like this reminds Animals (and animals, if they could read) why Kesha totally deserved her Wyler Award. Go girl!
