Why does she keep starving herself?

She looks like death. A beautiful and glamorous death, but death nonetheless. A perfect avatar for the deadened, boring, sterile today.

I don't have access to her body at the moment, so I cannot speak on her health.

She wants to get closer to all those poor little starving kids all over the world she is constantly babbling about. That's her take on method acting.

she's probably back on the heroin

She's crazy. I used to think it was just for the limelight but she's not a working actress no more. No reason to get keep it up. She doesn't even parade around the paparazzi. She's got a proper disorder.

That's her take on the principle of mass conservation and also her understanding of the basics of social work and involvement with UNICEF: If a wealthy white first world woman eats less - some kids in Africa eat more!
