I haven't been a Lady Gaga fan in quite some time now but I totally believe her that Azealia Banks had a bad attitude, resulting in them cancelling their collaboration.

I am a really big fan of Azealia Banks but I must agree that her behavior is not right. To be honest I think she needs to see a doctor about it, maybe she is bipolar.
One day she's happy and posting fun stuff on social media, the next day she is angry and saying racist comments.
