Madonna, Chris Rock and dozens of other celebrities raised $3.7 million Wednesday night at a star-studded benefit at the United Nations to help poor and sick children around the world.

The $2,500-a-plate dinner and live auction hosted by Rock was an unusual blend of charity and commercial promotion for the U.N. and made some of its officials, including Secretary-General Ban Ki-Moon, uneasy.

Gucci, which paid the costs, pegged the event to the Friday opening of its Manhattan flagship store on Fifth Avenue and put its logo and UNICEF's behind the walkway where celebrities were photographed.

The red-carpet reception drew stars such as Drew Barrymore, Demi Moore and Ashton Kutcher, Amy Adams, Brooke Shields, Salma Hayek, Djimon Hounsou, Dita Von Teese and UNICEF Ambassadors Tea Leoni and Lucy Liu, followed by a cocktail party with the likes of Donald Trump and media mogul Barry Diller.

Celebrities paid $2,500 to $10,000 each to dine on grappa-cured salmon, wild striped bass, tart of goat cheese, foraged mushrooms, truffled mashed potatoes and sticky toffee pudding with creme fraiche. Madonna played videos of Malawi and introduced children from the southern African country. Rihanna, Timbaland and Alicia Keys played music afterward.

Tom Cruise bid $100,000 for a sports package that included the privilege of hanging out at Yankee Stadium with Alex Rodriguez and a private hour playing soccer with David Beckham, but lost out to a bidder who ponied up $350,000.

''It was an extraordinary evening. The whole evening was quite moving,'' Cruise told The Associated Press, accompanied by his wife, Katie Holmes, who agreed. Cruise called the United Nations ''an absolute necessity'' because of the staff who dedicate their lives to building peace.

A trip to Paris with a tour of a vineyard and lunch with Francois-Henri Pinault and Hayek went for $120,000. The priciest auction item was a $600,000 winning bid to tour with Madonna and take a dance class with her and Gwyneth Paltrow.

Organizers said the proceeds would be collected by the Gucci Foundation, a registered charity, and split among Raising Malawi, an advocacy group that operates under The Kabbalah Centre International, and the U.S. Fund for UNICEF, which supports the United Nations Children's Fund.

Security was tight and few reporters were allowed inside the dinner.

Madonna has tried to help Malawi orphans since she and her husband, Guy Ritchie began raising a Malawian boy they want to adopt. Rights groups questioned her actions since she took him from an orphanage in 2006 at the age of 1. According to UNICEF, HIV/AIDS affects almost 1 million people in Malawi, including 83,000 children, and half of the country's 1 million orphans have lost one or both parents to AIDS.

''I've earned a reputation for many things: pushing the envelope, for being a provocateur, for never taking no for an answer. For endlessly reinventing myself, for being a cult member, a kidnapper. For being ambitious, outrageous and irreverent. And for never settling for second best,'' Madonna told the dinner.

''But I don't just want you to write me a check. I'm more interested in your heart. I want to take you on that journey with me tonight. I want you to feel as inspired as I do right now,'' she said. ''Yes, I want to raise Malawi. But if I can do that -- if we can do that -- then the sky's the limit.''
