One idea could be to surprise him with tickets to see Katy Perry in concert the next time she's in town. You could also get him a personalized Katy Perry t-shirt or hoodie with his favorite song lyrics on it. Another option could be to create a customized playlist on Spotify filled with all of his favorite Katy Perry songs. For a heartfelt touch, you could also write a love letter to him and include a Katy Perry-themed gift basket filled with his favorite snacks and goodies along with Katy Perry merchandise like stickers, posters, or even a vinyl record of her music.
Or you can get him a star map with the date of your first kiss.
