Amy Winehouse faces no further action in connection with her husband's alleged attempt to pervert the course of justice, police have said.
Blake Fielder-Civil denies both charges
Blake Fielder-Civil, 25, from Camden, north London, is charged with trying to pervert the course of justice and inflicting grievous bodily harm.
The singer was interviewed by police in December but is no longer required.
He pleaded not guilty to both charges at Snaresbrook Crown Court on Friday. He was remanded in custody until April.
The singer was questioned by police in December before being released on police bail to return for further questioning at a later date.
But on Friday Scotland Yard confirmed that she was no longer required to do so.
A spokesman for the singer said: "Amy is pleased to be discounted from the investigation and thanks the police for their professionalism in their dealings with her."
Mr Fielder-Civil is accused of attacking pub landlord James King at the Macbeth public house in Hoxton, east London, in June 2006.
He is also accused of conspiring to pervert the course of justice by offering Mr King money to withdraw his allegation and leave the country.
Mr King, 36, from Risley, Derbyshire, Anthony Kelly, 25, from Chalk Farm, north-west London and Michael Brown, 25, from Holloway, north London, also denied the conspiracy charge at an earlier hearing.
Grammy Award winner Winehouse, 24, did not attend the court hearing on Friday.
Her spokesman said the singer was absent because she was travelling to Paris to perform at a party for fashion designer Louis Vuitton.
