I had the privilege of meeting Melanie Chisholm. Otherwise professionally known as Mel C from the Spice Girls….
I met Taika Waititi. NZ is small as shit, and I met him in Wellington.
It depends on who you regard as the most famous.
I've hugged the band members of Bayside who have released 8 studio albums and well known if you like that kind of music. I've also chatted with Jimmy Carr the comedian after going to watch him. I also played with Peaches Geldof (Bob Geldof's daughter) after bypassing her security when I was a small kid at a park. Paula Yates was there and my parents were mortified.
Kevin Major, a Canadian author? Not that famous outside YA circles in Canada.
Alex Pangman, Juno-nominated jazz singer? Again, not that famous outside Canadian jazz circles.
James Nicoll, Hugo-nominated SF&F book reviewer and fan writer? Not sure he is known outside SF and RPG circles (he owned the gaming store where I hung out in the eighties).
Sadly, though, no one really, seriously famous.
I met Anne Lennox and Kate Bush, both wonderful singers, Kate Bush was quite shy. she liked my dress.
John Cuzack bought me a beer!
LJ got the stink-eye from Julia Roberts in a restaurant once.
My family has a long history with millionaires and billionaires, including Les Wexner and Jeffrey Epstein (yes, THAT Jeffrey Epstein!). He got rich conning Columbus billionaire Les Wexner out of a fortune. My father was involved in trying to get Wexner to sever ties with Epstein and realize he was a fraud, but Wexner fell for every scheme Epstein talked him into. We manage real estate for a lot of millionaires in Ohio, but other than the rich, the only famous person I've met is former Ohio Governor Ted Strickland.
Now, that would be telling.
Mikhael Gorbachev in the lift of the Dorchester hotel in London. I thanked him (through his translator) for making the world safer for my son who had just been born. Sadly this was a long time ago.
Then Vice President George Bush when I shook his hand on graduation day
Toss up between Leonard Cohen and Pierre Trudeau
Jimmy Barnes from Cold Chisel
Shane Douglas, Ric Flair, Eddy Guerrero. Plus a lot more pro wrestlers
i don't know that this is the most famous person i've met, but my favorite story of meeting a "celebrity" is the time i went to see Electric Six in a small-ish club in louisville, kentucky. the opening band hadn't started playing yet, and the crowd in the bar side of the club was starting to gather. my wife at the time had managed to grab a table, and we were sitting there watching a college football game on the tvs above the bar.
i look over at the bar and there stands Dick Valentine, the lead singer from Electric Six. we had two unused chairs at the table, so i sorta nodded at him and at one of the empty chairs. he came over and sat down with us and we talked football for a bit before he had to go get ready to play.
