I agree not everyone wants the super toned, super lean, bubble butt look. She might be quite happy with her figure.This is a bit of a radical concept, but perhaps Niomi is happy just being slim? Not everyone wants to be muscular, or follow the trend of a big bum or whatever.
If she was plus/midsized and people were making comments about her being flabby, all hell would break loose, but because she’s slim she’s fair pickings for body shaming.
But also this is a gossip forum so why are people not allowed to say what they think? I don't see how calling her flabby is worse than a lot of things that have been discussed and scrutinised on here.
