Who says all her fans left? I'd say the majority were disappointed but realized this is between her and Rob, and Rupert and his WIFE. Period. We are focusing on her career, and part of that is selling the movies she's made. Part of selling is putting yourself out there as an actress and being seen, and to do that one needs to put their best face forward. If she walked onto the red carpet looking like a homeless person critics would be making fun of her. She can't win no matter what she does or doesn't do.
