There's really no reason to believe it's fake. That's exactly how Nicki has always acted when she's mad. None of this is really the least bit surprising, honestly. But it's... sad. She should be celebrating her success unbothered but she continues to do the most over any stupid comment that anyone makes about her. Threatening that her murderer boyfriend is going to break someone's jaw is not fucking it. Though, I'm long past the point of expecting better from her. She's going to continue to let this shit overshadow her (mostly) excellent music. She's her own worst enemy.
