Robert Stack wouldn’t even touch this mystery with a ten-foot pole. The bedraggled Back to Black singer was spotted flashing some undergarments that suggest perhaps she’s gone back to diapers. German newspaper Bild is suggesting that the strange underpants being worn by Amy Winehouse and recently spotted by overly zealous paparazzi are adult diapers.

The shots were taken after Amy had returned from a visit to see her incarcerated husband of over one year Blake Fielder-Civil, but it’s unclear exactly what is going on underneath her dress. Amy did warn us that she was “no good.”

Considering the alternative might include her flinging her feces at us when angered, maybe a diaper isn’t such a bad thing.
