Bid low and win big.
Lady Gaga is auctioning off the silver triangular trio necklace designed by Brian Lichtenberg that she wore in the "Poker Face" video to the lowest bidder on Winnit.com, a reverse auction website co-founded by Nick Lachey.
The auction begins June 15 and ends June 24. All proceeds will go to Gaga's charity of choice, The Lupus Foundation. To participate, users must pay one dollar each time a bid for the lowest, unique amount is placed. At the close of the auction, the user who holds the bid closest to zero - and is the only person to hold that exact bid - will be deemed the winner. Bid on the necklace here.
The singer, 24, also auctioned off her white Mulberry handbag (along with Mariah Carey's Louis Vuitton clutch) at the S.L.E. Lupus Foundation's "New York Bag Ladies Luncheon & Celebrity Handbag Auction" earlier this month in New York City.
