The most followers on Instagram is not her doing. She has a PR company that specializes in that. In other words she bought those followers. Selena is getting those followers between her age and the fact that she is a cross section of Instagram aged Hispanics and American pop kids. She has also palled around with Miley, Bieber and Taylor so she is getting their followers as well. And then there is Disney.
If you want to give her an award for something, give her an award for going threw chemo while keeping her career going. She has Lupus. And with such health issues at a young age she is doing pretty well.
