You don't have to list them all, you can just write the total (although if you have a great story about meeting a certain celeb, feel free to share!)
I'm not sure how many I have met in total but I have photo's of me with 15 celebrities on my website http://www.freewebs.com/caribbean-queen
My favourite meetings were at my local carnival in 1999 when I met Liz Dawn & Bill Tarmy (Jack & Vera Duckworth from Coronation Street.) I gave Liz Dawn a card with a painting of where I live on the front and I have a photo of her reading it infront of me! She was so nice! I feel sad whenever I see the photo now as it reminds me of the fact that Liz had to retire so early due to Emphysema
