Kurt Cobain Back from the Dead?

Not really, but according to The Sun (UK newspress), Courtney Love, the rock 'n' roll widow, claims that she's been DEFRAUDED out of millions ... by Kurt Cobain.

That's right, according to Courtney, someone used the dead rocker's social security number to buy a $3.2 million property.

Smells Like Teen Spirit writer Kurt shot himself dead in April 1994, at age 27, making widow Courtney owner of 98 percent of Nirvana's grunge catalogue.

"I would like to know how," says Love. "He should probably get his ass back home if that is the case."

Courtney also claims that thieves set up 188 credit cards in her name!

"I knew it had been going on since when I went cuckoo - bananas - in 2003," explains Love. "It was fraud after fraud. But nobody believed me until now. I did a check on my deceased husband's social security number and he has a house in New Brunswick, New Jersey. He bought it last year."

Courtney met with police this week to investigate her claims.

"I know who they are," she says ominously. "Taking a child's money and future is a really horrible thing."
