Bella Hadid may be one of the most sought-after supermodels in the world, but her latest collaboration with Kourtney Kardashian's lifestyle brand - Poosh - has left several fans concerned about her weight.

Last week, Poosh - who describe themselves as "a guide to living your best life" - shared a picture of Hadid modeling a glamorously sparkly black jacket and black pants, worn to reveal jewel-encrusted lingerie.

Watch Bella and Gigi make history on the runway:

The caption read: "If you're currently uncomfortable in the bra you're wearing, keep reading. Link in Bio to figure out your correct bra size."

However, rather than focus on the subject matter, many commenters took aim at Hadid's appearance, with many focusing on her weight.

Check out the image in question below:

One Instagram user with the handle afb1975 commented: "Maybe this is just a bad photo but she really doesn't look well here. Shame."

Another, whydidyoudothatkarenn, commented: "She needs a burger or a big plate or 2 of pasta. So unhealthy looking".

Meanwhile, other Instagram users slammed Poosh for not promoting women of different sizes in their campaigns:

User rittenhouseperreault writes: "Do you ever show real women with curves? It seems like all your about is skinny Hollywood women needs".

And yvonne_around_the_world commented: "How about a picture of someone with a realistic body size rather than a super slim model?"

However, Hadid appears to have taken the comments like water off a duck's back, as she has now shared pictures of her posing in a tiny bikini in her kitchen.

Sharing the revealing snaps with her 27.7 million Instagram followers, Hadid captioned the post: "me on the 72nd hour of my phone deep in a bag of rice".

There's no denying that the 23-year-old looks incredibly, and the comments section was flooded with flame and heart-eyed emojis:

But despite the 1.3 million likes, there were still several people focused on Hadid's weight and slim frame.

User ooatbxbble commented: "BRUHHH I have a strong feeling she [has] an eating disorder", which was followed up by stepholiver45, who rudely instructed Hadid to "gain some weight".
