Definitely agree with this. Always found them both super creepy.
I'm in quite a celeb-heavy area, and most are very normal. I used to work in a pub once upon a time so came across a fair few.
The most famous tend to be rather distant, but polite. As you might expect. Some of the pop stars / DJs were very social, and we'd have some very good afterparties. Probably shouldn't name names!
Ian Hislop was pretty up himself, I was serving him at a pub many years ago and he wouldn't even look at me when ordering. And no, I wasn't beaming at him, or asking for an autograph. Just asked what I could get him to drink, and he promptly looked in the opposite direction and told his companion what he wanted rather than answer me.
Matt Aitken of Stock Aitken Waterman is deeply, deeply unpleasant.
My ex told me Vic Reeve was the worst human he's ever met, extremely rude and arrogant.
A friend works cabin crew and had Amber Heard in either first or business, she said she was the worst passenger she's ever had. She delayed a flight for ages as she refused to get off her phone. She also said Tony Blair was extremely off hand and arrogant, and would only communicate via his vast security team.
