Today, Lady Gaga is offering her “little monsters” are getting the opportunity to own a little piece of Gaga history.

The edgy singer has shown her softer side by donating a necklace that she wore in the Poker Face video — which made her a household name — to be sold for charity on “reverse auction” site, Winnit.com.

And OK! readers will get five free chances to win this awesome prize!smykke-1

The sale runs from June 15th to 24th on the site — co-founded by none other than 98 Degrees star Nick Lachey — where members win prizes by bidding the lowest unique amount of money on an item. So if you’re the only person to bid, for example, seven cents for the Brian Lichtenberg-designed necklace, then it’s yours!

Gaga has chosen The Lupus Foundation to reap all of the auction’s proceeds. Lupus is a chronic autoimmune disease that claimed the life of her aunt, Joanne, and that the star recently admitted having at a “borderline” level herself.

Bidders must first create a user account on the website to be eligible to participate. To claim your five free bids, enter the code “ok5” on the new member registration page.
