first of all, the amount of likes does not vindicate how pretty you are. If you are popular and know a lot of people you get a large amount of likes. There are some average people who get even more likes than that. All it depends on is how many people know her.
From what I can see, she looks like an attractive girl.. maybe the likes come from people who think the photo is cute with the sticker. Though it doesn't make sense to take a pic of yourself and cover most of your face with a sticker lol
