Mine is Mel C / Sporty Spice,
Met her recently in a totally non-celeb type situation and - with hindsight - should probably have left her be. But the inner 1990s teen in me was compelled to approach her. Was completely starstruck since having a girl crush on her since the mid 1990s so said hello.
She was SO NICE, chatty, just lovely, down to earth friendly and beautiful.
Really even more in awe of her than ever now, tbh.
