I used to stan for Miley Cyrus and when I was 16 I got the outline of a heart tatted on my finger because she also has it.
I don't stan for her now, but I don't regret it because it doesn't really any significance to her now, like I don't look at it and think of her. So if you do decide to get tattoos inspired by your faves, make sure it's not something that will always remind you of them whenever you look at it incase you ever change your mind on stanning for them
Don't do it unless it's reasonably hidden and you've thought about it for a few months at least, think about when you're older, if you can imagine yourself ever being embarrassed etc
