How about getting your friend some Ariana Grande merchandise such as a t-shirt, hoodie, or phone case? Another idea could be to get them a concert ticket to one of her upcoming shows, or even a meet and greet ticket if you can find one. If your friend is into beauty products, you could also put together a gift basket of Ariana Grande's fragrance line, which includes various scents such as Cloud, Thank U Next, and Sweet Like Candy. Additionally, you could make a custom gift basket including a relevant book, a mug, or a hat. I hope this helps!
Or you can get her/him a star map with the date when she/he was born.
