AMY WINEHOUSE's husband Blake Fielder-Civil has been ordered to serve a further 18 months in prison for beating up a pub landlord.

Fielder-Civil was sentenced to 27 months in custody at London's Snaresbrook Crown Court on Monday (21Jul08) after pleading guilty to causing grievous bodily harm (GBH) to James King.

He had also admitted conspiracy to pervert the course of justice by attempting to bribe King into withdrawing his testimony - offering him $400,000 (GBP200,000) to drop the case.

The 26-year-old - who married the Back To Black star last year (07) - has been held on remand at London's Pentonville Prison for the past nine months, meaning he has to serve a further 18 months before he is freed.

Before the ruling was announced, Fielder-Civil's barrister Jeremy Dein QC appealed to Judge David Radford to suspend his client's sentence, or sentence him to time served.

He told the court Fielder-Civil was "of exemplary good character", adding, "This has been a nightmare scenario, not just for him but for his wife and his family."

However, the plea was dismissed by Radford, who responded, "No previous convictions, rather than exemplary good character - if what I read about him and the use of drugs is true."

He added that Fielder-Civil had behaved in a "gratuitous, cowardly and disgraceful" manner.

Fielder-Civil's co-defendants Anthony Kelly and Michael Brown, both 25, and James Kennedy, 19, were also jailed for perverting the course of justice. Brown had also pleaded guilty to the assault on King.

Fielder-Civil was supported in court by his mother Georgette; Winehouse was not present for her husband's sentencing, reports Britain's Sky News.
