Britain's Got Talent - contestants fake?

Controversy hits this week as Britain's Got Talent is accused of creating fake / different back stories for contestants to make them more popular..

For example

A pair of brothers are accused of making themselves out to be "just sandwich shop workers" to increase their likability and appeal to a working class audience.  In reality they only work in their family's shop when they are not touring the world singing on a cruise ship having already released an album that has been mentioned on TV (see article below)

Another contestant was seen shaking with nerves and saying she suffers from stage fright which makes her more likeable as the audience feels sorry for her.  She has been accused of faking this because she was also seen appearing on the BBC show The Voice showing no signs of these nerves, as well as appearing confident and sexy on her You Tube channel (see article below)

Might be good examples of how "reality tv" cannot be relied upon to be "real" anymore.  How tv institutions are creating these Propp style characters (the hero, the underdog, the victim etc) to improve ratings because their real life personalities are not enough to raise ratings.
