Chris Evan's

[EmiliaBassano]

I've lost count of the number of times I've seen this written in various comments about radio and podcasts. Is it autocorrect?

Goodnes's know's. (Sorry!).
Seriously, I think it should be Evans' if it's about something that belongs to him.

Unless he’s called Chris Evan and we’ve been getting it wrong all this time

Autocorrect often tries to do this to me when I write about Dr Dewi Evans
