With pieces donated by Banksy, Damien Hirst, Jeff Koons, Richard Prince, and many more art heavyweights, the Sotheby's (AUCTION)Red at the auction house tonight is gearing up to be a collector's scrum. Christy Turlington, Dennis Hopper, and Mario Batali are all slated to attend, as is Michael Stipe, who already knows what he wants to buy. "I'll tell you, the Ed Ruscha is so beautiful" he gushed to New York's Fiona Byrne at Tuesday's Edun party at the Desmond Tutu Center in Chelsea "I think it's a 2007, but it's brought what he does full circle, which is part of the reason I am drawn to it. I am tempted to bid; I may well." Elsewhere at the party, Josh Hartnett told us he's watching the pennies after a recent large purchase. "I have to find out if I have any money left," he said, not ruling out the prospect of picking something up from the auction, which will go to help fight HIV/AIDS in Africa. "I just bought a new place and totally redid it and put in new furniture, but I have to get something for the walls!" Last night at a Gagosian Gallery preview, celebrities like Jon Bon Jovi, Anna Wintour, Donna Karan, Tory Burch, Russell Simmons, and Ivanka Trump were more hushed about what they wanted. But we think we can guess which painting caught Rupert Murdoch's fancy.… He spent the entire night standing in front of Damien Hirst's Where There's a Will, There's a Way. It's expected to fetch between $5 and $7 million tonight. Which, for Rupert, is probably a small price to pay for a piece of contemporary art that embodies your life philosophy.
