Just to put my .02 in.. I don't think the point is whether or not someone is PROUD of their weight. Maybe it's that word choice. What I believe to be important is that people are proud of who they are. Everyone is a work in progress whether a character flaw or whatever...
If you want to look at the whole idea of marketing, packaging, etc of someone like J Lo - you can rent the pretty crappy - but "funny satire of the industry, Josie and the Pussycats.
Like I said.. not a great movie - but it shows just how ridiculous the industry is as a whole when it comes to "stars"
