Lady Gaga is giving two lucky fans the chance to join her on tour for a day as part of a charity auction.

The Poker Face hitmaker will give the winning pair access all areas for a concert on her Born This Way Ball tour, a backstage meeting with her, entrance to the show's rehearsal, and prime seats for the concert.

The package, which is up for auction on CharityBuzz.com, is expected to attract bids of more than $25,000.

A description of the lot on the website reads, "Ever dreamed of being a pop star? Touring the country? Performing for sold-out arenas? Here is your chance to experience the tour of international sensation Lady Gaga!... Bid now for a day you will never forget!"

CharityBuzz benefits more than 1,000 non-profit organisations around the world.
