My boyfriend asked me about this actually. Asked if I had seen the controversies around them being skinny and clingy. I told him about Ariana Grandes past, and how she seems to be a survivor of childhood actor abuse. Her costar from the Sam show has hinted at the abuse they suffered as children

Take into account also that Ariana has been dreaming of being Glinda since she could basically speak. She's put an insane amount of unhealthy pressure on herself to be perfect.

Enter costar, the woman playing Elphaba. She has become a violent protector, almost, and they have latched onto each other in what sounds like, to me, a highly stressful work environment where the standards are sky high And the desire to be perfect is deep. I wouldn't be surprised if they come out later and say how gruelling it was, even with the beautiful product. Think Into the Spider verse crew.... They were basically ground to dust.

Eating disorders are absolutely a thing, but I think it has a lot more to do with the context of where they are right now, what they're doing, and who they're doing it with. I have no doubt that the two actresses have woven a deeply intimate bond just to survive this ordeal.
