Jessica please quit pissing on everyone's leg and telling them its water. If you want to get your career back then you should take this advice:
Quit lying.
Saying things like "I am not dumb, I just pretend like I am dumb" is desperate. This is the classic line of dumb people who wish they were smart, but aren't smart enough to say something smart.
Secondly, no one believes that you are a size 2. I understand that "admitting" to being a size 2 in hollywood is like admitting that you free base the cream out of Twinkies. However; the people in hollywood are not your fans, trust me. The regular people, who buy your shitty CD's and hair extensions, think that a size 8 is skinny. You could be honest about it and people would be far more forgiving. Another option? Fire the person who dresses you. If that person is you, you are really screwed.
Thirdly you are not an actress or a country singer. You are a blonde pop singer with a B- voice. You have a nice rack and that can get you far in the world. There is no shame in embracing your assets. Pretending that you can act and sing country music, is just an insult to humanity.
There are worse things to be in the world than dumb and pretty.
