A Valentine's Day card written by Amy Winehouse to her former husband is set to go up for auction later this month (Dec13).

The late singer was married to Blake Fielder-Civil from 2007 until 2009, and a loving card she once wrote to him is expected to fetch up to $3,000 (£2,000) when it goes under the hammer at Bonham's auction house in London on 18 December (13).

Original handwritten lyrics to Winehouse's track Love is a Losing Game will also be included in the sale.

A spokesman for Bonham's tells Britain's Daily Star newspaper, "These things were acquired by a friend of Amy and Blake's who would sometimes hang out with the pair."
