Kristen Stewart was on the 'Blackkklansman' Premiere At Cannes Film Festival, and when she got to the stairs, she did what any female in that position would WANT to do, but doesn't ever act on it: She took off her shoes and walked up the stairs. Mind you, she didn't have on a long dress either, so she just barefooted it up for the world to see - which I honestly, find very admirable.

Totally with you KStew. I would rather go barefoot than try to walk up the stairs and have a "Jennifer Lawrence" incident.
