Literally bumped into Chris Evans (ginger not Cpt America) in Chinatown in London. I turned a corner and wasn't looking as I was talking to a friend. He was also talking to one of his (huge) entourage and we collided. He's very tall.
Sid Owen (Rickaaaay) at the Blue Rooms in Bath. He was a regular there and usually barged his way to the bar literally saying 'do you know who I am'. But then was pissed off when people would holler 'Rickaaaay' at him.
Andy Day (of Dinosaur et al Adventures) was in front of us in the queue to collect our Wicked tickets from the box office at Bristol Hippodrome. I was a bit excited about that. I got a selfie with him in the box office and was a hero on the school gate the next morning after sharing it on the mums WhatsApp group. He ended up sat in the row behind us, but at the end. Directly behind us was Justin Lee-Collins.
I used to live in Borehamwood so pretty much the entire cast of EastEnders circa 1992. Gillian Tayleforth (Kathy) used to drive round with her child on her lap.
Robert Lindsay parked next to us at a services on the M4 (roughly near Reading).
I swear Cuba Gooding Jr walked past me just off Times Square.
Frank Bruno and the entire cast of Birds of a Feather on Wimbledon Common (at different times)
DH was in the same pub as Chris Tarrant years ago, two tables over.
