ive just looked her up
She certainly is beautiful and looks amazing but no, not empowered. I can only repeat what others have said about how being morbidly obese is.
Most big celebrities carry their weight in ways that look sort of ok. They seem to be fairly firm, often without huge double chins or multiple rolls, nice skin etc.
The majority of very overweight people are really wobbly, with celulite, hanging rolls/multiple rolls etc so they look nothing like fat celebs.
In terms of the health needs and mobility, often they're quite young so the impact isnt as great but they wont be 'healthy' as such
So no, its not empowering, its a bit like heroin chic and glamourising drug use or anorexia, no one thinks thats empowering if a celeb is an addict or has an eating disorder the talk is about getting treatment and help, not staying as you are.
No one should be mocked or shamed for what they look like but neither lauded for carrying too much weight
