Have あなた ever met a celebrity? (ex: conventions, some ランダム 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 ジャケット and at the time I didn't know about Critical Role または 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 あなた guys? Have あなた met any celebrities?
