Reality TV stars
What people tend to forget about reality tv stars on the show is that unlike the tv presenters or pop stars etc this is their day job and they are very professional about it.
A case in point was Joey Essex; a vapid jack-the-lad who goes in proclaiming they can't even boil an egg...
...fast forward 4 weeks and they are cooking beef wellington with truffle shavings and a port reduction.
I always wonder who is training/coaching them and whether it is stage managed by the show itself (or their agent)? There is just no way they are growing into self taught chefs this quickly.
Absolutely nothing wrong with taking it seriously but it makes it feel a little bit hollow when you realise they are almost certainly just repeating recipes that've been drilled into them by a cookery coach.
I think the same probably goes for a lot of the sports stars that excel in the show too.
