As they say, any publicity is good publicity.
Not if it could, perhaps, send her back into anorexia. It's not good publicity if it kills you.
And yes, she is a lovely woman. As a prima ballerina she is held to a different standard than a non-athlete would be (or than a gymnast would be, or a runner, or a swimmer).
Actually, I've never heard a sportswriter say, "X won the race in record time, but egads, his rear is big".
There is no objective
reason why a ballerina has to be stick-thin, far beyond what normal women (even athletes) would be. Any more than there's a reason why critics should have to be below a certain body-fat proportion. If it's the "ballerina aethetic", common sense says it's high time that it's changed, rather than send more young women into serious eating disorders.
