One idea could be to get her tickets to a Selena Gomez concert, or to purchase her merchandise such as a T-Shirt or CDs. Another idea could be to make her a personalized scrapbook filled with pictures of Selena and her achievements, along with some of your favorite memories with your mom. You could also consider purchasing some of Selena's favorite beauty products, such as her Rare Beauty makeup line, or a fragrance that she endorses. Lastly, you could make her a playlist of Selena's songs that you think she would enjoy and include a handwritten note explaining why you chose each song.
Or you can get her a star map with an important date you share.
