Lily Allen - Allen Wants $1.5 Million Charity Donation For Morgan Chat

The Smile hitmaker is one of Morgan's dream guests for his British series Piers Morgan's Life Stories, which has garnered huge ratings thanks to revealing interviews with former U.K. leader Gordon Brown, pop star Cheryl Cole and music mogul Simon Cowell.

But Allen, who miscarried a baby in her sixth month of pregnancy last year (10), has made it clear she has "no interest" in an in-depth chat unless Morgan persuades bosses at the ITV network to donate the huge sum to SANDS, a U.K. charity which helps parents who have lost children.

In a post on her Twitter.com page, she wrote to Morgan, "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. A charity that helps women to overcome the kind of grief that I have had to experience. I'd do it for a million for SANDS. Money, mouth?

"Those are my terms. I've got no interest in coming on your show, you've been asking me for years."

The America's Got Talent host agreed he would organise an undisclosed five-figure sum for the interview, replying, "I will get ITV to make substantial five-figure donation to your charity for the interview. Think about it."

However, Allen is sticking to her original terms, simply responding, "No."
