World Vegetarian Day is being celebrated on 1 October, 2015 (Thursday). It's the day that promotes joy, compassion and life-enhancing possibilities of vegetarianism. It brings awareness to the ethical, environmental, health and humanitarian benefits of a vegetarian lifestyle.

On this day, we list out some of the hottest Hollywood celebrities who will inspire you to give up meat for veggies.

Miley Cyrus: How can we draw a list of hottest vegetarian celebrities without mentioning the name of PETA's sexiest vegetarian celebrity of 2015 --- Miley Cyrus. The singer and actress gave up on meat and animal products after a coyote killed her beloved pup Floyd. She had once posted a picture with a lot of veggies on her plate and captioned it: "The luxurious life of a vegetarian in LA... So many good plants/fruits/veggies to eat you ain't gottttta eat dead animals! Everything that goes into my body is aliiiiivvvve! To keeeep ME alive! Love this life!"

Peter Dinklage: The "Game of Thrones" actor became vegetarian at the age of 16. He had once admitted that he quit on meat back in his teen for a girl, but continues to be a vegetarian till date for the love of animals. "I like animals – all animals. I wouldn't hurt a cat or a dog, or a chicken or a cow. And I wouldn't ask someone else to hurt them for me. That's why I'm a vegetarian," he said.

Jared Leto: The actor who will be next seen in the film "Suicide Squad" as the Joker, attributes his youthful good looks to yoga and vegan diet. The actor who has been a vegan for over two decades, said: "I'm pretty healthy so I think that helps a lot. I've been that way for a long time -- 20 solid years of eating vegetarian/vegan and taking care of myself. That probably helps the preservation process. I'm a vegan. I respect the environment and I do my best to spread the importance of such an issue."

Ellen DeGeneres: In 2008, the 57-year-old host became a full-fledged vegan. Ellen is known for her kindness to fellow human beings, but she's also kind to animals. Once a steak and sausage lover, Ellen expressed why she chose to become vegan on the PETA blog page. "I personally chose to go vegan because I educated myself on factory farming and cruelty to animals, and I suddenly realised that what was on my plate were living things, with feelings. And I just couldn't disconnect myself from it any longer. I read books like Diet for a New America and saw documentaries like "Earthlings" and "Meet Your Meat", and it became an easy choice for me," she wrote.

Gwyneth Paltrow: The "Iron Man" actress has confessed that she was persuaded into becoming vegetarian by Leonardo DiCaprio. She had been suffering from various health problems before switching to veganism and it has worked wonders for her. She's created various recipes and put them together with details of her diet in her new book: "It's All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great."

Brad Pitt: The actor is an ardent animal rights activist, who had confessed that he hates it when wife Angelina Joile and their children eat animal-based dishes. One of his strongest arguments is about the damage caused by methane gases from cattle and that should be a reason strong enough for his family to go veggie.

Russell Brand: The British comedian became a vegetarian at 14, after watching a documentary "Forks over Knives." He once said: ""Even as a junkie I stayed true [to vegetarianism] - 'I shall have heroin, but I shan't have a hamburger.' What a sexy little paradox."

Tobey Maguire: Tobey Maguire has been vegetarian since the early '90s and is working towards a completely vegan diet. Maguire has been able to make vegetarian alterations to his diet, allowing him to bulk up for 'Spiderman' and drop weight for "Seabiscuit."

"I've never had any desire to eat meat. I don't judge people who eat meat -- that's not for me to say -- but the whole thing just sort of bums me out," he once said.

Christian Bale: "The Dark Knight actor took to vegetarianism when he was 9 years, after reading the childhood classic, "Charlotte's Web". Bale grew up with an animal rights activist father, who taught him to always be compassionate towards animals.

Paul McCartney: The former Beatle member Sir Paul McCartney, and his late wife Linda, were both avid vegetarians and animal lovers. The singer who turned vegetarian after a fishing trip, has been quoted as saying, "If slaughterhouses had glass walls, everyone would be a vegetarian."

Ariana Grande: The Nickelodeon star and two-time Grammy nominee, Ariana was voted as PETA's sexiest vegetarian in 2014. "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-round happier person," the singer told of her decision to go vegan.

Natalie Portman: The actress has been a vegetarian since childhood and she even refuses to wear fur, feathers or leather. "Part of my reason for being vegetarian was because it practices respect and love for life all through the day, so three times a day, you make a decision to eat things that have not been killed," she said.

Jessica Chastain: The actress in fact got her mother -- Jerri Hastey, a chef -- to switch to veganism as well. Jerri owns and operates a vegan food truck, Seed on the Go, in Santa Rosa, California. While expressing her thoughts on being a vegan, she said: "I don't normally get into this, but I'm a vegan. And I try not to, well, I don't want to torture anything. I guess it's about trying to live a life where I'm not contributing to the cruelty in the world... While I am on this planet, I want everyone I meet to know that I am grateful they are here."

Ellie Goulding: The singer announced that she was a proud vegetarian on her social media accounts early this year. "I am a vegetarian (in case you didn't know), I feel healthy and happier than ever before. My body is grateful," the "Burn" singer wrote on Instagram in June 2015.

Alicia Silverstone: The 38-year old actress and activist has been a vegetarian for nearly two decades. In fact, she has even written a vegan cookbook, "The Kind Diet," and launched a blog, "The Kind Life", that focuses on vegan and vegetarian food, environmentally-sensitive fashion items, and environmental issues.

She has been famously quoted saying: "Once people spend time with farm animals in a loving way ... a pig or cow or a little chicken or a turkey, they might find they relate with them the same way they relate with dogs and cats. People don't really think of them that way because they're on the plate. Why should they be food when other animals are pets? I would never eat my doggies."

"Nothing's changed my life more. I feel better about myself as a person, being conscious and responsible for my actions and I lost weight and my skin cleared up and I got bright eyes and I just became stronger and healthier and happier. Can't think of anything better in the world to be but be vegan."

Pamela Anderson: The most famous of all, the Baywatch star gave up eating animal products when she started working with PETA. And the actress continues to promote a meat-free life till date. This year, in April, she toured an Arizona jail to promote vegetarian meals in prisons and then, in July she launched a vegan cooking web series. There are reports that suggest that by the end of the year she will debut two lines of vegan accessories.

Anne Hathaway: This actress has had an on-again, off-again relationship with vegetarianism. But after her break-up with the fraudulent Raffaello Follieri, it was reported that Anne has given up on meat and fish again. And it has also been reported that, when she is a vegetarian, she is most inflexible and rigorous vegans and she always asked for "cruelty free food" on the set of her movies.
