Nicholas Lyndhurst is a bit grumpy, he shops in my local M&S and he tries to be so unobvious (hat, sunglasses) that he is in fact, really obvious

Jamie & Harry Redknapp are really nice (Jamie is sooo handsome too)
Lee Mead is really nice and Sarah Lark (from "I'd do anything") is amazingly lovely.
Christopher Timothy is quite funny.
I met Same Difference (XF4) in a club, and they were chatting to fans for ages! They were nice!
Matthew Kelly is a big grump.
