That is true.But it doesn't have to do with Mariah only.We expect celebrities to be model perfect.It is not accepted to gain weight.We do not forgive that.Do you remember what happened with Jessica Simpson?She had gained weight and everybody talked about it.The same goes for Oprah Winfrey-actually in her case the criticism has never stopped about her flunctuating weight-,Tyra Banks,Kristie Alley and the list goes on.
