I'll start with the lovely ones...
Dermot O'Leary in M&S - v friendly and happy to chat away to the checkout ladies
Ed Milliband visited my workplace. He was much taller and very surprisingly far more handsome and dashing than he appears on TV. Very kind and listened to people longer than he needed to.
Michael Palin on Hampstead Heath - seemed very nice
Bill Nighy - sightseeing in Paris, seemed nice and chilled
Reece Shearsmith at a party - absolutely lovely and a sweetheart
Tobias Menzies (Prince Phillip in The Crown) - worked with him- absolutely lovely and v modest
Hugh Grant in a pub in Soho, he was really normal and polite to onlookers and just trying to have a quiet drink with his mate. He drove off on a moped.
Clare Skinner - the mum from Outnumbered- lived near me and I used to see her dog walking. Very nice and normal.
Sean Bean - at an event - really nice and down to earth even though loads of people were swarming round him!
Emily Thornberry - in the theatre with her kids. Seemed like a normal mum.
Juliet Stevenson in a theatre loo- quiet and avoiding eye contact
Josh Widdecombe - in Hackney- seemed normal enough
Melanie Sykes - sunbathing in Ibiza - seemed ok, had very 'cool' friends
Chiwetel Ejiofor - backstage at something - seemed a bit too aware of his own celebrity but ok
Caroline Flack- rehearsed for Strictly in my gym! She was a bit impatient with people talking to her but tried to come across as friendly-ish. Iyswim.
Scott Mills- same gym- he was a bit of a diva!
Rufus Hound - a bit of a knob
Elton John (and his DH) at a press night - he was so stuck up, kept his face stony and wore shades indoors
Zawe Ashton - I worked at an event she was at- full of herself / arrogant
Stephen Daldry, Billy Elliot director, worked with him- incredibly self important and fake
Dairmund Gavin I think his name was - the tv gardener? In a pub in Notting Hill. Drunk, leery and pervy.
Dwight York- pinched my bum when I was an 18 yo waitress
Bill Kenright & Jenny Seagrove - served them as a waitress - both very rude and entitled and full of themselves
Tom Allen the "comedian" / presenter of Bake Off / You're Fired. Worked in an office where he was working once- he was a complete twat- arrogant and bitchy.
Janet Ellis - ex Blue Peter presenter and mother of Sophie Ellis Bexter. Worked on something with her. She was a typical catty / bitchy type.
