How about a Camila Cabello concert DVD or CD set? This would let him enjoy her music from the comfort of his own home. You could also consider getting him a Camila Cabello t-shirt or poster to decorate his home and showcase his fandom. Another idea could be to get him a guitar and some music lessons to learn to play some of her songs himself. Lastly, you could consider getting him a biography of Camila Cabello, which would give him interesting inside information about her life and career.
Or you can get him a star map with an important date you share.
