The husband of British pop singer Amy Winehouse, whose recording success has been overshadowed by a torrid private life, is seeking a divorce, the lawyer acting for Blake Fielder-Civil said on Monday.

"I can confirm that I have been instructed to commence divorce proceedings on the grounds of Amy's adultery," solicitor Henri Brandman said.

Winehouse's representatives confirmed the move.

"Papers have been received and the matter is with Amy's lawyers," a spokesman said.

Fielder-Civil and Winehouse married in Miama in May 2007, but since then Winehouse has attended a rehabilitation clinic for drug addiction and Fielder-Civil has spent time in prison after pleading guilty to beating up a pub landlord in 2006 and conspiring to cover up the crime.
