Rock star Courtney Love claims that Amy Winehouse does more drugs than any of her previous party pals.
The widow of late Nirvana frontman Kurt Cobain says that Amy has even left her behind in taking hard drugs.
"Amy does more drugs than anyone I've known," the Sun quoted her as saying.
Courtney also says that Amy "speedballs", taking a deadly mix of cocaine and heroin.
Courtney and Kurt were dubbed "the new Sid and Nancy" in the Nineties, but Amy and her husband Blake Fielder-Civil are the latest couple to take the dubious title.
Amy reportedly suffered a massive drug overdose last month after taking a cocktail of booze and drugs including heroin and cocaine.
She, however, told her pals that she only took heroin for the first time less than six months ago.
