(Cover) - EN Showbiz - Lily Allen has told Piers Morgan she would only agree to an interview with him if he donates to a charity helping women who have experienced miscarriages.

The British pop star, 25, and her fianc Sam Cooper experienced heartache back in November when Lily suffered a miscarriage with the baby she had been carrying for six months.

Lily is reluctant to discuss the tragic ordeal, although chat show host Piers whose new programme Piers Morgan Tonight for CNN will premiere in America on Monday night is keen to talk to her.

In an exchange on social-networking site Twitter, Lily told Piers she would only open up if she knew money would be donated to help women who have lost unborn babies.

# @piersmorgan I don't need to enhance my career Piers, the only way I would justify coming on your show would be to give money to a charity (sic), wrote Lily.

The singer would want a large donation made to UK charity Sands the stillbirth and neonatal death charity, as she greatly admires the work they do to help women experiencing the same ordeal she went through.

# @piersmorgan i'd do it for a million for SANDS. money, mouth?????????????????? (sic), Lily challenged the television star, describing the organisation as a charity that helps women to overcome the kind of grief that I have had to experience.

After her tragic end to 2010, there was at least some happy news. The singer got engaged to Sam on Christmas Day as the couple enjoyed a romantic break in the Far East, and Lily has been enjoying planning her nuptials. (C) Cover Media
