Amy Winehouse's guilty husband Blake

Amy Winehouse's husband Blake Fielder-Civil has pleaded guilty to charges of assault and attempting to pervert the course of justice...

Fielder-Civil, 26, has been cooling his heels in the pokey awaiting trial since November 2007.

The UK Daily Mail reports that during pretrial arguments last week he changed his plea from guilty to not guilty, admitting that on June 20, 2006, he assaulted James King, the landlord of Macbeth's pub in London.

He also pleaded guilty to a charge that he conspired to pervert the course of justice by offering King a bribe to withdraw his allegations and leave the country.

Fielder-Civil is expected to receive up to three years in prison.  He also could receive a fine and/or more time in jail for the added bribery charges.

Winehouse was not seen at London's Snaresbrook Crown Court when her husband pleaded guilty.

Recently a cache of embarrassing photos and video surfaced of the two taking drugs, and posing in sexually ambiguous settings surrounded with drug paraphernalia.
