I don't agree with those prostitutes setting that guy up. Thought it was such a nasty thing to do.
Yes, I have seen one famous person - saw him twice. He turned up looking just as he did in the papers (this was a while ago), and I thought it was someone wanting me to think it was this person. I said to him "Oh you look just like ....." He smiled shyly and asked what I thought of this guy. I said I thought he was awful what he did to such and such a person. He said "well theres always two sides to a story". I always kept myself to myself, but this man from a local brothel rang me and asked if Id seen this guy. I said I had seen someone pretending to be him. He tried to convince me it was the real person (from what I have seen, they usually give a fake name but the name usually starts with the first letter of their real name) and wanted me to do a story with them on him. I said no. Then it was splashed all over the sunday papers a few months later.
If I'd have known it was this guy, I would have told him to bog off.
