This is actually an amazing business move. It's such a lucrative industry. There's this woman in Australia named Belle Gibson who started a healthy living/vegan app/series of book who pretended the lifestyle cured her of cancer, which she never had. She scammed so many people and became a millionaire. It was really controversial.
But yeah, the industry is huge. I give it a month until it's more profitable than TIDAL and the hive will be bragging about it as if it was their own money.
Yea it's not that serious. Some of these fans be doing the most to get attention.
But as the poster above me said, this vegan diet will make her earn a lot of money. It is just giving her authenticity to set up her Topshop athletic line launching the end of the Summer.
