Amy Winehouse 'Suing Ex-Mother In Law'

Amy Winehouse is allegedly taking legal action against her ex-mother in law.

The Sun reports that the troubled singer is suing the mum of former hubby Blake Fielder-Civil, for selling a love letter Amy wrote to her ex-lover while he was behind bars.

The paper says Winehouse wants £50,000 in compensation, as it's claimed Blake's mother Georgette broke copyright laws by publishing the private note.

"Amy was furious the private letter was used to make money." A source said.

Yesterday the singer apparently told another paper that she is "still in love" with Blake, despite them getting divorced in June.
