The Rehab singer's father, Mitch, has spoken out to the Daily Mail about his troubled daughter's situation... and it turns out that the 24-year-old has emphysema.

Such sad, sad news.

"With smoking the crack cocaine and the cigarettes her lungs are all gunked up," says Mitch. "The doctors have told her if she goes back to smoking drugs it won't just ruin her voice, it will kill her."

Mitch adds that Amy's imprisoned husband Blake is also trying to get clean, but he warns her drug dealers to "take responsibility." Oh, and he definitely doesn't want Amy "hanging out with her mates like Pete Doherty either." Well, duh!

Can Amy do this? We sure hope she can!
