Ariana Grande stopped doing interviews after being called a diva.

Ariana Grande is harmless in my book. After the doughnut licking incident, she was hated for quite some time. Then public perception of her changed.

Her concert was bombed in Manchester, she was sexually assaulted at Aretha Franklin's funeral, and then her ex Mac Miller died suddenly. She went from hated to sympathized. Her amazing redemption arc was mostly down to how well she handled the aftermath of the bombing. Fast forward to three years later, and Ariana no longer wants to be called a diva. She's stopped doing interviews because her words would get twisted. She's strong, and I think she's established and well respected enough now to do a Beyoncé where she gets to control the narrative of how her interviews are conducted.
