One idea could be to get her tickets to see Lady Gaga perform live, if she's touring near your area. Alternatively, you could also consider getting her some Lady Gaga merchandise, such as t-shirts, posters, or albums. Another option could be to purchase a book written by Lady Gaga herself, such as her autobiography "Channel Kindness", or her photo book "Lady Gaga by Terry Richardson". You could also consider getting her a Lady Gaga-inspired jewelry or fashion accessory, like a statement necklace or a unique pair of sunglasses.
Or you can get her a star map with the date when she was born.
