John McCririck (I really can't spell it!) in the Ivy. Disgusting table manners and ignoring his rather plain wife.
Madonna running in Hyde Park with someone I assume to be her personal trainer.
Ulrika Johnson "running" in Hyde Park, but quite frankly I can crawl faster. She was a most peculiar orange colour.
Victor Meldrew in a newsagent in Wimbledon (he was in Panto).
Annabel Croft shopping in Wimbledon.
Annette Crosbie walking 2 yappy dogs on Wimbledon Common.
Robson Green walking down the Broadway in Wimbledon.
Andrea thingy, the weather girl on GMTV in Debenhams taking her DS to the loo (also Wimbledon - noticing a theme?!). Only clean loos in Wimbledon, I think.
Sat opposite Philip Glenister and Keeley Hawes on the tube last summer. She was quite loud and showy-offy, but also rather tall, thin and gorgeous and wearing a lovely shirt/dress thing. I went straight out and bought something similar, but being a curvy 5-footer, the effect really isn't the same!
Judith Chalmers in Marylebone looking less tanned than she does on TV.
Chris Evans in Marylebone - surprisingly tall and looks rather older in RL than I expected him to.
Must be loads more, being a Londoner, but I can't remember back much further than six months!
