The long-awaited film "Wicked" has started its promotion with the stars who are part of its cast.

But, recently, Ariana Grande and Cynthia Erivo seem to be getting more attention than the movie itself, due to drastic changes in appearance.

During the promotion of "Wicked" in Los Angeles and in London, Ariana Granda appeared weaker than ever.

According to international media, there is a possibility that the singer suffers from malnutrition and lipoatrophy.

Dressed in a bustier dress with an open neckline, the singer appeared thinner than usual.

Fans have also expressed concerns about her weight and appearance on social media in recent weeks. 

"She's skin and bones," someone commented. "Ariana looks very very skinny," wrote someone else.

Hollywood has long been accused of promoting unrealistic standards of beauty. One of the earliest and most tragic examples is Judy Garland. She underwent brutal weight loss strategies while filming The Wizard of Oz.

Fans are concerned whether Grande's and Erivo's changes are part of the same strategy.
