They tried to make me go to the dentist, I said no, no, no...

London, UK -- Amy Winehouse has donated a tooth she had lost to meth abuse to help out Haitian earthquake victims.

The controversial "Rehab" singer made the impromptu announcement at the Regent Street Tesco in London while out shopping for a pack of cigarettes and flip-flop sandals earlier today.

"She was walking through the condiments aisle when she had the epiphany and decided she needed to announce it right there and then," said Winehouse's UK publicist Chris Goodman. "She called me right that instant and I scrambled to organize a hasty press conference in front of the old bloke that was handing out Kleenex coupons. Sincerest apologies to him."

"This is for Haiti obliterated," said Winehouse to the crowd of reporters and bystanders. The singer immediately left the store after making her brief speech, leaving her publicist to field questions.

Goodman said he is pleased by Winehouse's decision, but admitted it took him by surprise.

"That tooth had been her lucky charm. She wrote most of 'Back To Black' whilst sucking on that sweet putrid thing," he said. "Needless to say, this is a huge, huge thing for her."

The details are still being worked out, but Goodman said it is "already nearly fairly certain" that Christie's in London will be carrying out the auction. Goodman is confident the loose tooth, which Winehouse herself extracted during a meth-induced episode of paranoia, will fetch bids as high as half a million pounds Sterling.

"This tooth is a piece of modern pop culture history, and it deserves to be revered as such," said Goodman.

Winehouse is the latest in a growing number of famous celebrities coming forward and reaching out to the disadvantaged people of Haiti.

Earlier this week, Britney Spears announced she is auctioning off a dress she wore to the 2008 MTV Video Music Awards and donating the proceeds to organizations helping victims of the Haiti earthquake.

Last week, a widely-televised telethon organized by George Clooney raised over $57 million USD in donations. The Nielsen Co. announced Monday that an estimated 83 million people saw at least a brief part of the fundraiser broadcast Friday by more than 30 television networks. The audience watching the two-hour event at any given time averaged 24 million viewers.
