As a fan of Zayn and as a stan of Azealia, I honestly think that they're both in the wrong. First of all, Zayn was wrong for coming at her. Like.. what was the point of coming for a woman who only have a fraction of the success you have?

Also, Zayn/his Twitter stans are TRASH for leaking Azealia's personal information. Imagine all the personal information that's on her iCloud. Contact info, credit card numbers, unreleased music. If I was Azealia, I'd really consider suing either Zayn or his stans (I don't know who actually leaked it) because that's not funny.
On the other hand, Azealia is a MESS for those racist jokes. Those jokes aren't funny. She's also a mess for leaking his FaceTime (although I doubt that's his real Facetime because Azealia most likely has no connections with Zayn and/or his team).
Please keep in mind that I just got home so I don't completely know the entire saga, but this is my opinion just based on what I've heard and saw so far.
