the island I lived on was seething with off-duty celebs, but I never met any of them.
I once saw Heather Graham in a local restaurant. she wasn't wearing makeup, and looked a bit tired. my cousin rented a boat to Michael J. Fox. she said he was really nice.
I met a fugitive former international hash dealer on the run from INTERPOL - does that count?
I was an extra in a movie with Gerard Depardieu, but I never met him. I got paid $75/day to pretend to drink fake beer, though.
