I do not get this. Why do stars check into the damn hospital from "exhaustion"? I mean, why can't they just take a few days off and hide at home in bed for a few days like any normal person would do with "extreme exhaustion" - or when we would get shitfaced we would just call it "hungover". Still, same remedy, hit the bed and hibernate for a bit and get over it.
Unless she was in there to get her blood changed, ala Lizzie Grubman (which just seems absurd and gross to me), then I can see having to go to the hospital for that one.
