What are some relatively harmless celeb stories that you've heard that still make you go "yikes"?

For example: Lorde talking about swimming in the Potomac river , which isn't problematic (in the sense that it's not racist, homophobic, sexist etc) but still made me go "oooof" when I heard about it given the water contamination.

​

Does anyone have any similar stories about celebs doing weird/odd/potentially regrettable things that aren't morally problematic but still seem like a questionable decision?
