The eccentric singer has designed an entrance that will, 'create the illusion of walking into the mouth of a giant monster-like Lady Gaga,' Contact Music reported.
Christmas shoppers will then be able to head to 'a jewellery shop created out of an oversized Lady Gaga-turned-spider and a boudoir in the shape of a giant wig.' Then they can head to the fifth floor to forage amongst gift ideas, toys, clothes, make-up and CDs all personally chosen by the Poker Face star.
The fun will last from November 21 until Christmas, with a portion of the gifts being used to benefit the singer's Born This Way Foundation.
