Huge shocker -- crack, cigarette and who-knows-what-else smoking trainwreck Amy Winehouse has a lung disease.
Winey's father, Mitch, spilled the beans on her hospitalization, admitting the 24-year-old has contracted emphysema -- the same disease Johnny Carson died from when he 79.
Mitch told the Daily Mail, "With smoking crack cocaine and the cigarettes her lungs are all gunked up ... She's got 70 per cent lung capacity."
Amy has been in the hospital since collapsing in her London home last week.
