Big News for the vegan community this week, as Beyoncé and Miley Cyrus both revealed they joined the lifestyle. Beyoncé made her announcement on 'Good Morning America', taking her time on stage to promote her new business venture '22 days nutrition.' Miley Cyrus used her newest, high-profile cover on Papermag to announce she went vegan.

Why did she make this choice? Papermag doesn't actually quote her, but tells the story. It goes back to last year, when she was touring her "Bangerz" platinum album, taking her Alaskan Klee Kai "Floyd" with her.

She really loved her dog and was devastated when a coyote killed it, prompting her to quit animal products almost immediately.

Since then, the artist did not share lots of details about her new, plant-based diet. But she has reached a point where she thinks she can serve as a role model, using her fame to raise very pressing issues. She now wants to be "held accountable." Some vegans have reacted strongly about this, making the distinction between eating a plant-based diet and going full vegan, which extends to refusing to wear fur, leather and other animal-derived materials.

Cyrus did not elaborate on that. 

Her veganism comes hand in hand with other social activism causes she's been embracing, which might sound odd to those used to hearing about her because of nude videos, pink armpit hair or reckless 'twerking'. She shares with Papermag some of her experience with the Happy Hippie Foundation, a non-profit she founded also last year to help homeless people and LGBT youth.

Living in Los Angeles, it's hard to ignore the homeless crisis; yet that's what people learn to do, as it's so prevalent in certain areas, from Hollywood Boulevard to Downtown. "I see it all day: people in their Bentleys and their Rolls and their Ubers, driving past these vets who have fought for our country, or these young women who have been raped," she told the magazine. Feeling the weight of her privilege, she decided to raise awareness and help those in need through the Foundation.

The reaction to Papermag's issue has been mixed, as it features explicit nude pictures of the 22-year-old artist with very creative poses and colors. But the issues that she raises in the interview - animal wellbeing, homelessness, transphobia - are much more than one could expect from the "Wrecking Ball" singer, who is now recording her next album on a studio in her garage.

As for the vegan news, they come in the aftermath of Beyoncés announcement, albeit for different reasons. Queen B explained she adopted the new lifestyle in order to lose weight, which she always struggled with. Her fans were expecting a new album or tour, so they vented their disappointment on social media.

But for vegan activists, two major celebrities joining the likes of Ariana Grande, who's also vegan, is major – and positive – news.
