A New York City benefit auction has raised $1.4 million for four environmental groups, including the Central Park Conservancy.
Christie's "The Green Auction: A Bid to Save the Earth" also will benefit Conservation International, Oceana, and the Natural Resources Defense Council.
Among the celebrities attending the Tuesday night event were Salma Hayek, Ted Danson and Sam Waterston.
One of the top lots _ a chance to spend a day with former President Bill Clinton _ fetched $100,000.
Christie's says a companion silent online auction will run through April 7 on http://www.ABidtoSavetheEarth.org. Bidders can hope to take a tennis lesson with John McEnroe or fly to Miami to meet Lady Gaga.
