She's been big for years, you can see from other pics
This was here in 2019:
And a few years ago:
Obviously there's a big difference between these pics and the pics from yesterday, but she's been a big girl for a while, it just looked more manageable because she has big implants and she still had some kind of waist, although I would think in the pic from 2019 she's wearing some kind of corset. But yesterday she obviously did gain even more weight and is also not working with a glam team to contour her face and everything else
