Neither do I. Apparently, Alicia herself or somebody she knew found somebody somewhere in the world calling her "fatgirl" or "buttgirl" and Alicia talked to the media about it. It wasn't something anybody noticed before that. Even when the story came out the media had enough sense to put "allegedly" in their stories.
I have no doubt she got pressure from the producers and whatnot, but I don’t recall any fans calling her fat or making any major thing out her body or weight.
That movie got savaged justifiably so, but I don’t recall any major fan uproar about how she looked in the costume.
I do recall the costumes of Robin and Batman being mocked mercilessly for their gay look abs nipples…
But I don’t recall any major fan trashing of Silverstone for being or looking fat.
I am sure a troll or two may have but a big fan uproar about it? Not at all.
I have no doubt producers and folks in the industry probably pressured her about her weight and how she looked… but the fans?!? Nope
