Blake Fielder-Civil is accused of attacking a pub landlord - and then later conspiring with him to withdraw as a witness at the trial.
Fielder-Civil, 25, has pleaded innocent to the charge of assault, and is expected to plead Feb. 29 to a charge of perverting the course of justice. The landlord, James King, denied the conspiracy charge Friday.
The 24-year-old British singer-songwriter - her newly platinum-blond hair looking bedraggled - came to her husband's support at the hearing, blowing kisses before yelling out: "I love you handsome, gorgeous one."
Then, addressing reporters: "I am not talking to you."
Winehouse had been known for her black hair and massive beehive hairdo.
Last month, she was photographed walking outside her London home wearing a bra and jeans, with no shoes, looking distressed.
