Mariah Carey Now Synonymous With Crazy?

Howard Stern was on this morning talking about how Usher recently talked about his busy schedule and how he fears that under all the pressure he “might pull a Mariah Carey.” Howard thought it was interesting that Mariah’s name is becoming synonymous with being crazy, especially from the rappers [hey Howard, Usher doesn't rap, he's R&B!] that she’s trying to identify herself with.
