A lot of people are saying this tattoo is fake. Keep in mind Zayn has 68 tattoos already, so nothing would surprise me.
Here's the thing though, Zayn has yet to post any images of himself with the tattoo, except the announcement pic.
The funny thing, he has posted some pictures of himself with long hair again. Either he's been taking classes at Hogwarts, or he's screwing with all of us.
