I have met loads of famous people, but not while window cleaning, so my best is the producer from real radio phone in victoria, I clean hers mums house and will be doing victoria's shortly, and the security guard on a job I do quarterly is the brother of the black guy, on the programme boys from the black stuff, he is gay and gets all excited when when we put on full harnesses to go do the outsides from a safety line on the roof
but apart from that no, not window cleaning chat with famous people
