omg, yes! i've totally noticed it too, lately rakshanda has gained a lot of weight, even when we see her on kasam se, or jodi kamaal ki, sometimes her whole image looks very manly, because she's become so big. and it doesn't help that she's big boned as it is. she used to look very beautiful earlier on when she was slimmer.
also, i'm not trying to pass a judgement here about the whole smoking thing, but i just wanted to say that her smoking would explain why her teeth are so horribly colored.
i know that we shouldn't judge ppl on their choices, but if these actors are on tv, and if they're personal choices are affecting their appearances on tv (ie. teeth and weight), then i think that we viewers have a right to comment on them.
not trying to start an argument or anything, it's just my opinion.
