1. Ellie Goulding

The extremely talented British singer-songwriter admits being vegan is a challenge, but that doesn’t stop her from hitting her nutrition goals.

“I call myself an aspiring vegan. It’s challenging, but not impossible. You just have to eat or drink a lot of greens. I make green juice for myself almost every day. I put in things like bananas, avocado, spinach, broccoli—whatever’s in my fridge, really. Sweet-potato fries and salad is my absolute favorite thing. It’s the perfect meal. I eat a lot of quinoa and nuts too, but I also love eating chips. It’s actually easy to be a bad vegan because a lot of junk foods are vegan!” ~Ellie Golding

2. Miley Cyrus

Miley is undoubtedly one of the most well-known vegans in the music industry, and her transition into veganism started at an early age.

“The reason that I started this was because I had a fish that was highly intelligent. He really knew who I was, he really got excited when I was home. One day I went to a sushi restaurant with a few of my friends and they were serving blowfish. And I thought, this is an intelligent animal.” ~Miley Cyrus

3. Ariana Grande

In November of 2013, Ariana decided to entirely change her diet to vegan with health and happiness being her biggest motivators.

“I love animals more than I love most people, not kidding. But I am a firm believer in eating a full plant-based, whole food diet that can expand your life length and make you an all-around happier person. It is tricky dining out, but I just stick to what I know — veggies, fruit and salad — then when I get home I'll have something else.” ~Ariana Grande

4. Joaquin Phoenix

Joaquin was a large influence on Ellen DeGeneres’s decision to go vegan, with his extremely powerful narration of Earthlings the documentary.

“I’ve been a vegan since I was about 3 years old and involved in animal rights for years. I’ve seen a number of animal rights films throughout the years, none has affected me as profoundly as Earthlings.” ~Joaquin Phoenix

5. Natalie Portman

Once a vegetarian for 20 years, Natalie transitioned into eating 100% vegan in 2009 after she read Jonathan Safran’s Eating Animals, and now refers to herself as a vegan activist.

“Everyone has to find what is right for them, and it is different for everyone. Eating for me is how you proclaim your beliefs three times a day. That is why all religions have rules about eating. Three times a day, I remind myself that I value life and do not want to cause pain to or kill other living beings. That is why I eat the way I do.” ~Natalie Portman

6. Liam Hemsworth

Some might say it was Miley Cyrus’s influence on Liam fully committing to veganism, but he himself claims otherwise.

"I have a lot of friends who are vegan. Woody Harrelson was actually one of the original reasons I became vegan, because he’s been vegan for, I don’t know, 30 years or something.” ~Liam Hemsworth

7. Ellen Page

10. Ellen DeGeneres

As one of the most famous television personalities, Ellen has been a vocal animal advocate in the past and uses her famous show to bring awareness to the mainstream audience.

11. Woody Harrelson

12. Casey Affleck

An avid animal rights advocate, Casey urges his fans to avoid meat, calling it “poison” not only because it is the product of animal cruelty, but also because it is a health nightmare.
