Well I will ignore the obvious one, because I don't fancy living in Barnet, and I can't see a move to the East Midlands on the cards for you know who.
Otherwise the only possible plus I can think of in living next to any celeb is that I would be in swish accomodation myself, and probably living my life like an international pop star.
If pushed though, possibly Dawn French ( I could borrow her frocks) or Eddie Izzard, because I could so do with a laugh right now
