She’s got pictures on most of her social media accounts from just a few years ago where she says she weighed over 300lbs.
She slimmed down quite a bit, but her ass/hip really blew up this past year. There are a number of compilations on her subreddit of videos of her from over the last year where her ass gets progressively larger, but the rest of her stays about the same proportions.
I’d guess she’s had a number of fat transfers done, but I don’t know (I think she’s says she’s “natural” but I can’t quite remember where I got that from).
In any event, I hope it’s not silicon injections that have killed other models :-/
