Just as George Clooney and Scarlett Johansson auctioned dates with themselves on eBay to raise money for charity, Spears is now using the Internet site for a good cause, reports FemaleFirst.
Spears, 26, posed for painter Daniel Maltzman in only her knickers. The painting will be sold to the highest bidder on eBay and proceeds will go to The Promises Foundation, which helps low-income mothers and their children.
Spears, who autographed the artwork, hopes to raise more than $15 000 for the charity.
