Singer LADY GAGA is auctioning off the chance to spend a day behind-the-scenes of her North American tour to raise money for charity.

The Poker Face hitmaker will invite the lucky winner and one guest to experience 24 hours on the road with her when she takes her Born This Way Ball shows Stateside next year (13).

The highest bidder will be granted a personal meet-and-greet session with Lady Gaga, as well as a photo opportunity backstage and a goodie bag.

They will also be able to sit in on band rehearsals, explore each department of the tour and later enjoy the evening's concert from a VIP seat.

The once-in-a-lifetime experience with Gaga, listed on auction website CharityBuzz.com, is expected to pull in around $25,000 for Sports Spectacular.

The charity supports Cedars-Sinai Medical Genetics Institute, which aims to help manage and prevent genetic diseases.
