Blake Fielder-Civil, 26, was being tried in London on charges of attacking pub landlord James King, and then conspiring with King to have the landlord withdraw as a witness.
Fielder-Civil and three-co-defendants pleaded guilty last week, but a court order barred reporting the pleas because King is scheduled to face a separate trial. Judge David Radford lifted the reporting restriction Monday.
Soul diva Winehouse and Fielder-Civil married in Miami in May 2007. He was arrested in November and has been in jail awaiting trial ever since.
Winehouse has become an international star since she released the Grammy-winning album "Back to Black" in 2006. But her music has been overshadowed by reports of her drug use, run-ins with the law and tempestuous relationship with Fielder-Civil.
In the latest tabloid storm, Winehouse defended herself against allegations of racism after a newspaper published footage of her singing a racist ditty.
The video - filmed by Fielder-Civil sometime before his arrest and published Sunday by the News of the World - shows Winehouse and another woman singing a string of racial epithets to the tune of a children's song.
Winehouse later told paparazzi outside her north London home that she was sorry, adding: "I don't want to play anything down, but I'm the least racist person going."
Winehouse's spokesman did not immediately respond to a request for comment from The Associated Press.
Winehouse was at London's Snaresbrook Crown Court last week for the opening arguments in her husband's trial.
Fielder-Civil faces a maximum of five years in prison for the assault charge. Perverting the course of justice carries a maximum sentence of life, though that is unlikely to be imposed in this case.
The defendants are due to be sentenced later.
