Have tu ever met a celebrity? (ex: conventions, some misceláneo coffee shop, backstage/on set, etc)

I met Matt Mercer (Critical Role) at GenCon a few years ago. I was wearing my Attack on Titan chaqueta and at the time I didn't know about Critical Role o that he was even into RPGs, I just wanted to meet Levi from Attack on Titan :P I got a picture taken with him and we did the salute from AOT

He was a really awesome dude :)

What about tu guys? Have tu met any celebrities?
