"You can choose your friends, but you can't your family..."

Is there ANY hope for Lindsay Lohan's younger sister? I mean, with the parents she has, and the sister she has, could there be any hope at all that she won't be totally screwed up?? At the age of only 17, she's already modeling and has gone from what she used to look like (photo to right) as opposed to what she now looks like (photo to left.) When asked by a New York magazine if she had plastic surgery, she flatly denies it.
Why doesn't anyone ask her what she's eaten over the last 48 hours??
