Ariana Grande is sparking a lot of concerns regarding her health.

The star's recent public appearances have many in shock as she appears to be at her thinnest on the red carpet for the Wicked premiere.

The celeb stepped out for a photocall while donning a cream toned gown with a bustier. This exposed her chest while she celebrated the long-awaited arrival of the film on the big screen.

Fans of the celeb cannot get over her very slender appearance. And while many agree that she's always been thin, this recent appearance of hers has people stunned.

Many hoped she was doing well in terms of her physical and mental health. Another started to speculate about her eating disorder and perhaps that was the reason behind the significant amount of weight loss.

The star chose to step out with her long blonde tresses pinned far from her face in the pictures.

The singer's weight is now a subject of great debate online as some cannot help but call her a walking hanger or someone with just skin and bones. What do you think?
