My Grandad used to chauffeur people from Heathrow to their hotels. He once asked me this question:
"Do you know a singer called Justin Timberlake"
"Yeah..."
"Oh, I drove him to his hotel yesterday, very nice bloke.. very quiet, didnt know who he was though..."
This was when JT had some major records out!
My Dad also helped consierge some filming they were doing at his work which starred Keira Knightly, I whatched the filming but didnt meet anyone. Sh was staying at out local pub/hotel and decided to take a walk around the village. whilst she was out, i think my Dad popped up for a pint with a few work mates, he was walking back home when who should walk past but Keira herself. Thinking that Dad would recognise her from helping her at work, she says "Hello", dad says hi and continues home...
"Dad, Keira Knightleys staying at the pub"
"Who?"
"The one whos doing the filming, the one whos the girl in Pirates of the Carribean"
"Oh her... so thats whos just walked past me"
And Johnny Depp has a house like ten mins away from me, but im yet to meet him....
