Lol, it'd be much harder for me to find an opposite sex crush, seeing as I'm lesbian.
Alas, I don't pay attention to celebrities.
The closest to a celebrity that I'd say I have a 'celebrity crush' on is Field of Reeds, AKA Kristin Naigus. She is a professional oboist/English horn player and has contributed to video game OSTs and even songs from Steven Universe. She inspired me to pick up the oboe, which ended up with me returning to college. My stupid heart just had to grow a little attached. Liking her even helped me get over my ex. LOL.
